UICPAL ESP32 S3

AliExpress

Specs

• ESP32-S3 with 16MB flash memory, 8MB PSRAM (qspi), 3D antenna, RGB led, Camera and SD card reader (SDIO 1bit)

Pinout

SD:

Function	GPIO
CMD	39
CLK	42
D0	41

Camera: CAMERA_MODEL_UICPAL_ESP32S3

RGB Led: WS2812_PIN 33

Warning:

The UART converter on this board requires DTR and RTS to be disabled in order to receive Serial output.

In Platform.io, add the following lines:

monitor_dtr = 0
monitor_rts = 0

Or if using arduino-cli, use the following arguments:

$ arduino-cli monitor --port COM5 -c baudrate=115200,rts=off,dtr=off

Arduino IDE does not support this board invidually and hacking the system files feels too much efforts. An easy workaround is to temporarily switch to “ESP Dev Module” when debugging and switch back to “ESPS3 Dev Module” when compiling.
