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.

The circuit diagram can be found here:

and the pinout:

The pin definitions

LED 2: power LED
LED 1: user LED: GPIO 34
LED 3: NeoPixel: GPIO 33
SW 1: user switch: GPIO 38
SW 2: reset switch
