The ESP32-S3-FN8 CPU board

This page shows the hardware connections of the onboard devices provided be the ESP32-S3-FN8 CPU board. First of all, this is an ESP32-S3 CPU with 8MB of PSRAM and 16MB of flash. Then it has

  • a user programmable LED
  • a neopixel
  • 2 switches
  • a MSM261S4030H I2S microphone
  • a OV2640 camera
  • SD card holder
This board therefore seems to be ideally suited to run the TinyML demos.
