---+ 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.
