List of working Hardware (Add your links)

[caco3]

There is a lot of hardware around which looks OK but does not work. The reason are various:

• Missing, broken or too small PSRAM
• Unsupported or broken camera
• ...

This discussion wants to list vendors/products which are known to be working.

‼️ Please only add links to vendors/product which work for you. Unrelated comments or questions will get deleted (use a separate discussion for them)!

‼️ Please keep in mind that all those vendors buy in China, so in the worst case they get a batch which is ok and another batch which is bad! This also applies if you order in China directly!

Can you confirm if they work?

[caco3]

As stated above, all hardware listed in this discussion should be working!

[caco3]

As noted in #2041 the second link seems now also to send boards with only 2 MB of RAM!

[jakobschou]

First link send me a 2 MB module - and it has been removed aswell

I bought this in November, which work (but are too expensive in comparison).
https://www.amazon.de/dp/B08P1NMPLL?psc=1
Vendor was "diymore"

€dit: please don't buy this. See answers below

[ss89]

I know where to find the wiki. I wanted to raise a PR to add my unlisted Variant of the chip.

[caco3]

they are just seeing stuff from nowhere as they are not really in front of a meter

You could use the demo mode, see https://jomjol.github.io/AI-on-the-edge-device-docs/Demo-Mode/

Does anyone know how to add it to the webpage? i didn't see a gh-pages branch on this repo.

We have a separate repo for the documentation.

On the top right you see a link "Edit on Github".

Feel free to fork it and create a pull request. We are happy about any support!

Hello everyone, I bought my modules (2 pieces) from the same seller and they work!
After a few hours of trying and searching for the right drivers, I became aware here on Github that this could be due to the different PSRAM modules. These differences in PSRAM modules can cause the modules do not work (?).
I am using a PC (Win10) and I could not connect via USB/COM. I could not successfully install the drivers for the ESP32 USB module (CH340C).
Maybe I'm too stupid for that. It didn't work for me. In the Device manager, under "Ports (COM & LTP)" the following was displayed: "Silicon Labs CP210x USB to UART Bridge (COM5)". Under "Properties" the following device status was displayed: "This hardware device is not currently connected to the computer. (Code 45)". I've tried different micro USB cables.
Like I said maybe I'm doing something wrong here!? If anyone has a solution I would be very grateful. I think it could be the PSRAM modules.
I've tried different micro USB cables. The status light on the module lights up permanently "red" after connection via the USB port.
--> I was to stupid! I used a wrong USB-cabel! And thanks to "caco3"!!! The webInstaller now works fine!

My two modules, which I bought in a bundle, differ as follows in terms of construction and labeling:
I. ESP-PSRAM32 - 112017 - NA6Z-N876
II. ESP-PSRAM64H - 122021 - 130046G

I didn't find these modules in the GitHub list, so I'm sharing it here.

They work (product from Amazon):
diymore ESP32 CAM Development Board WiFi/Bluetooth ESP32 DC 5V Dual Core Development Board with 2640 Camera TF Card Module

[caco3]

on windows, there is no need to install a driver! did you try with the Web Installer?
Please creat a new discussion, this is not the right place for seup questions!

[denkplatz]

Thank you caco3 you gave me the right hint! You can record my ESP-PRAM specification in the table.

[Slider0007]

I bought my three devices here two month ago. They are all working.
https://www.berrybase.de/esp32-cam-development-board-inkl.-ov2640-kameramodul

Unfortunately, right now, out of stock...

[JohNan]

I bought one of those boards but I get the following error

The PSRAM chip has the name ESP PSRAM64H 402021 1A0017N

@Slider0007 Any idea why my board wont work as expected? Did you get a different PSRAM chip on your?

[Slider0007]

@JohNan: Sorry to hear that it's not working on your side. Your error message states that PSRAM chip is not properly detected, either elctrical connection or chip is bad.

My three working boards have a different PSRAM chip: AP MEMORY 6404L-3SQR-1120B 130028G. Unfortunately, it seems you cannot derive functional boards from buying source. For some reason it's quite random if you get a working one or not...

Are you using the device with this adapter board and USB port? If I remember right, somebody stated that it's worth to try it without that board to surly exclude electrical impact.

[JohNan]

Thank you the your reply.

Im using a CP2102 of this kind https://hitechchain.se/iot/cp2102-usb-uart-board-micro to power and flash the device. I flashed tasmota in hope to get some more info out of the board and using their Berry scripting command tasmota.memory() i got the following result with no mention of PSRAM at all. So I guess tasmota also didn't detect it:

{'heap_free': 19, 'program_free': 1645, 'program': 1234, 'stack_low': 3, 'iram_free': 32, 'frag': 14, 'flash': 4096, 'stack_size': 8, 'flash_real': 4096}

I have just ordered a AI Thinker branded ESP32-CAM and hoping that it will work better.

[jamesmsith324]

Hi @JohNan, did the AI Thinker ESP32-Cam work?

[McAiA]

AP Memory 6404L-3SQR 1120A 130027G => 8MB works

[DenBir]

This works fine https://amzn.eu/d/9jqdGxG but only the ESP32 Cam module (without the "bridge").

[caco3]

what do you mean with "bridge"?
The ESP-CAM-MB? That just provides direct USB access.

[DenBir]

Yes, right.

[mule1972]

Yes those are working, but from four I ordered only one was ok. Two had a not functioning flashlight and one a not functioning cam. Those chinese boards are really mostly crap.

[faberlau]

Hello, I currently have three devices in use.
I bought them all here: https://www.ebay.de/itm/402577872913
So far they work without problems.

[scalt]

I bought 4 of them. Will test it out and provide feedback asap.

[alexbergsland]

The link is dead.

[ede-kowalski]

Hi all,

my 2 modules from the first post arrived.
Unfortunately again not enough PSRAM....

regards,
Ede

[rvbaelen]

did somebody tried to replace the psram module? :) i can find the module, but i'm not sure this even shoud work? I got 4 camera modules... do luck so far

[Kitsok]

Hello!
Doesn't work:
6404L-3SQR 11207 130024G from here https://www.amazon.nl/dp/B0B56BDBMC?psc=1&ref=ppx_yo2ov_dt_b_product_details

[JanneN9]

Hei,

https://www.aliexpress.com/item/1005002808966055.html

• initial setup without antenna very difficult, disconnection but after that 2 of those work fine

Terveisin
Janne

[caco3]

The slow responding resp. disconnects most likely do have nothing to do with the module. I guess your wifi reception is too weak. The external antenna should improve this. Please also have a look on the RSSI on the overview page (bottom right corner).

[JanneN9]

True,
Now it is located very near router, so working nice without antenna.
Result: WIFI Signal: Good (-59dBm)

[magicus]

Just a warning: I ordered one from the same seller, and got one with a problematic PSRAM which does not work. :-( So it seems a bit hit or miss whether you get a working one or not.

[Jandaduns]

Just wanted to let you know that I was able to correctly flash (and use) an ESP32 CAM module with the label 'AP MEMORY / 6404L-350R / 1120A / 130027G' on the PSRAM module. Perhaps you can update the hardware compatibility page to reflect this. It showed 8Mb of RAM. https://jomjol.github.io/AI-on-the-edge-device-docs/Hardware-Compatibility/
Obtained from: https://www.otronic.nl/esp32-cam-development-board-met-camera-wifi-en-blu.html
Note the board delivered reported 8Mb of RAM (although the listing at Otronic said 4Mb).

[uwen70]

I bought two working modules here on 2/2/23: https://www.amazon.de/gp/product/B091F4ZZF6
It has 8Mb PSRAM and the USB board has only one button.

[Boeng01]

Bought those on 04/15/23 - One didn't flash at all, one just 2MB PSRAM

[Norm71]

Up and running for 12+ hours with no issues so far.

[chgoeldi]

I also ordered one. It was especially easy to flash with the onboard mini usb and the built-in flash button. However, I don't get it to work and I see that the PSRAM is AP MEMORY / 6404L-3SQR / 13100 / 180026G which is known to not work according to https://jomjol.github.io/AI-on-the-edge-device-docs/Hardware-Compatibility/
Does your board have a different PSRAM or did you get yours working nevertheless?
Mine is constantly rebooting every 3min and the log shows...

Thanks for the tip, testing now. Seems that's missing in the setup procedure?

it works, thank you so much!

[schneich]

I have bought two of those on 11.4.2023, which got delivered last week. I only tested one, but that was easy to flash and seems to work. be aware that this is one board, including wifi antena and USB. The board is a little bit longer and does not fit into some cases, you find on thingiverse.

[karstengit]

Buyed an ESP-Cam at Ali-Express that should have 4MB and get one with only 2 MB PSRAM.

There are other offer, that specially advertise with 8MB PSRAM, but of course you don't know what you really get.

[git2fa]

Here is a recommended supplier: https://www.aliexpress.com/item/1005004749706289.html
Ordered 4 of them and all could be flashed with the AI Firmware and the camera is working.

The modules have OV2640 2MP camera and 8MB PSRAM with this type of PSRAM:

Tried 2 of these guys from AZDelivery, not working correctly. I assume the modules can't read correctly the SD cards (I tried multiple SD cards, brands (Sandisk...), size (2G/32G), AI on the edge firmwares...). I asked for a refund.

So which cam did you buy?

[zafzafzaf]

I bought this one (120° 21mm Version)
https://aliexpress.com/item/1005006020785680.html

It is recognized and working without any problem. But I did not try and calibrate on the counter yet

[sixtyfive]

Hmm, so many different lenses. 120° isn't too bad of a compromise between cylinder length and image quality, I guess.

[sixtyfive]

These here sensible people also make a USB-C MB. Much more convenient nowadays.

As I read few comments about having problems with other esp32cam + Mb boards and do not need the mb to flash, I decided to use mini and micro usb versions(to make use of the old cables I still have home) of this breakout board:

I just ordered this ESP32 development board on amazon and it works fine.

[doctorkb]

These seem to work: https://www.amazon.ca/dp/B0948ZFTQZ

This does not: https://www.amazon.ca/dp/B0CJJHXD1W (camera didn't connect, wouldn't see SD card)

This one works fine

I bought the JoyIT DEBO ESP32CAM module from Reichelt:
https://www.reichelt.de/entwicklerboards-esp32-kamera-2mp-25--debo-cam-esp32-p266036.html

(Don't forget to buy an USB-Serial Adapter if you don't already have one cause this module has no USB Port).

I got three modules. The datasheet states 4MB PSRAM, but it comes with an APS6404L-3SQR (64 MBit) and the log also reports 8MB.

The lens seems to be glued in place with superglue, which caused quite a hassle to get it free.

Hi
does anyone has experience with the M5stack camera series ?

expecially this one that seems well housed and well done

based on ESP32 S3 wroom 1 (ESP32-S3-WROOM-1-N16R8) with 16Mb flash and 8Mb PSRAM

[arzaman]

Anyone with this nice HW ?

[scottlamb]

That looks very nice, but the ESP32-S3 is a totally different architecture than the ESP32-D0WDQ6, so there's no way the same firmware binaries would work on both, and there's likely significant effort involved in making ones for the S3.

Hi, can you tell me how you flashed the firmware? I had a different ESP32 module which I just plugged in and flashed it, but with this board, I just get the red light and maybe the flash light, but I can't get a COM connection to the PC.

[RedWolf112]

Hello, I don't remember exactly. But I think it was something like holding down the flash button and plugging in the USB cable

How did you manage to get the APKLVSR to boot? I have one, but I'm not getting a USB connection. My other ESP32-cam modules work fine, so I'm trying to determine if this board is faulty.

[editwentyone]

no idea what you mean, it just worked?!

[Puma7]

no idea what you mean, it just worked?!

so, now i can give feedback. The boards worked, but all of my 3 micro usb cables don't. My recommendation: Thest your usb cable first 😄

[Xeevis]

Yeah. That's the most common issue and sole gripe I have with whole USB. Who cares that connectors fit when it's very random if things will even work. Finding matching source, cable and end device is like playing "match 3".

Septic Usage Tracking with ESP32-CAM

First, thank you so much for this project.

I'm using this in the US for an unusual purpose—tracking my septic usage. We've been having issues with our septic system for a few years, and this, coupled with an hour meter, will provide invaluable data.

Current Setup

ESP32-CAM

Aokin ESP32-CAM Bought the two pack and both worked.

External Antenna

IPEX Connector 2.4GHz WiFi Antenna

MicroSD Card

SanDisk 4GB microSDHC Card

USB 5V 2A Power Supply

USB 5V 2A Power Supply

Case and Modifications

I've made some modifications to this ESP32-CAM case to better suit my setup:

• Added a slot for the external IPEX antenna.
• Widened the cutout for the USB port.

Note: I can provide the modified STL file later if anyone wants it.

Additional Details

This specific ESP32 CAM board, required switching the 0 Ohm resistor from on-board antenna to the IPEX connector. I didn't have any SMD soldering tools, so this part came out a bit sloppy.

This setup has been working well, and I'm happy to share any insights or further modifications as needed. If anyone has similar use cases or needs assistance, feel free to reach out.

Thanks again for this amazing project!
