Hmm, the 5mm Blue diffused led is quite bright tbh. I've set it with a small resistor, 470 Ohm.

3.3V and 1.13 mA. Does that make sense? I'm still getting to grips with my multimeter and my electronics knowledge.

I've figured it out. Pin.PIN_HOLD does the job, but it's usage is a bit confusing at first. There are three things to keep in mind: - if an GPIO value has been held previously, you can read it's current value only by creating the Pin with pull=machine.Pin.PULL_HOLD - in order to be able to update th...

Thanks, but I'm using an Adafruit Feather: htps://cdn-learn.adafruit.com/assets/assets/000/041/630/original/feather_schem.png?1494449413

Does it have anything similar?

I'm hoping to be able to read the USB battery voltage so that I can predict when it's about to run out of juice.

For ESP8266 I've found https://github.com/micropython/micropyt ... -242315810 to work nicely. Is there something similar for ESP32?

Basically all I'm trying to do is keep a LED on while the board is sleeping.

I've came across https://github.com/micropython/micropython/pull/4561 but I have no idea what to make of it.

Thank you both for steering me in the right direction. I've managed to strip Adafruit's drivers down to the essentials and this is what works for me:

I've published the code and usage instructions at https://github.com/mihai-dinculescu/mic ... ter/seesaw.

I wonder if it's possible to use the Adafruit STEMMA Soil Sensor with an ESP32 board running MicroPython.

Any tips to steer me in the right direction will be greatly appreciated.
