In this tutorial, we will explore the pinout of the XIAO ESP32S3 and its related board, the XIAO ESP32S3 Sense, and learn how to use these pins for different purposes. Specifically, we will cover the usage of 1x UART, 1x lIC, 1x lIS, 1x SPI, 11x GPIOs (PWM), 9xADC, 1x ...
First solder on pins and connect your Xiao ESP32S3 to the expansion board. Then connect a grove connector cable between the Grove SHT31 and one of the I2C ports on the expansion board.To test this setup we can use an existing sample with Zephyr: west build -p always -b xiao_esp32s3...
After dumping 40 hours into this time sink and 2 board revisions later, I'm asking for help. I designed this board after following the ESP32-S3 datasheet and the schematics of several existing espcam boards with the intention of running the OpenIris firmware that's based on the Arduino ...
