    Found a demo referencing data.sparkfun.com, I tried to visit the site but it seems to not be working. Is this service still alive? Edit - Checking Forum...

    The hardware overview says "2x UART (only two are configured by default in the Arduino IDE, one UART is used for bootloading/debug)" Are there 3xUART where one is dedicated to bootloading and 2 are available or are there 2 in total?

      There are only 2 UARTs available on the ESP32-S2 module. I'll try to reword that statement to be a little more clear.

    Hello, great article! I'm wondering is it possible to read battery status programmatically?

      Measuring the remaining charge on a connected battery is not an inherent capability of this product; you'd have to add an additional sensor. However, you might be interested in using this SparkX board, which has a built-in battery fuel gauge sensor.

    Seems like there is a mistake in the Hardware Overview section for the Primary I2C Bus.

    In this document it says that SDA=IO2 and SCL=IO1, but they are actually swapped. On the board itself the labels are correct.

    SDA = IO1 and SCL = IO2

      You are correct! Nice catch, I just updated that table.
