This project created to show ISM 2.4 GHz spectrum on SSD1306 or SSD1331 OLED's on Pololu Wixel, Arduino Nano, ESP8266 or Raspberry Pi.

Structure

This project helps to biuld spectrum analyzer on different modules. It contains next Pololu Wixel subprojects:

• Wixel with SPI and/or I2C OLED's SSD1306
• Wixel with ADF4351 and SPI and/or I2C OLED's SSD1306 (noise generator)
• Wixel with two SPI and/or I2C OLED's SSD1306
• Wixel with SPI OLED SSD1331

And another subprojects:

• Raspberry Pi 3 and Pololu Wixel with SPI and/or I2C OLED's SSD1306
• Arduino Nano v3 and TI CC2500+PA+LNA with two SPI and I2C OLED's SSD1306
• Arduino Nano v3 and nRF24L01 with I2C OLED SSD1306
• ESP8266-1 with I2C OLED's SSD1306 Spectrum
• ESP8266-1 with I2C OLED's SSD1306 APs List
