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...
I believe you are refering to phant, which was retired a few years ago. There are other similar services linked in the post.
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.
