It runs on an ESP32-C3, which means the USB-C port only runs in JTAG mode - so no possibility of pulling power from it.

HOWEVER, you can get ~1mA of 3.3V off of the D+ pin, which is juuuust enough to dimly light a single red LED.

This means you can have a reading light powered by the device, although this is an entirely cursed way to do this, and hardly enough to read by.

Basically just uses the USB-C on the ereader as a “mount” then

What a goofy accessory hahaha

Unironically your hack is better because it doesn’t require charging the light separately. Even if it barely puts out light 😂

This is a cool project

I didn’t look too closely but I saw that they offered a light accessory and I think it is powered via it’s USB-C port

However, when you have access to all of the hardware (including the battery), there are definitely easier ways to do this.

This project is great, though - I actually have a specific use case for it, potentially.

Abusing pull-up resistors for fun and no profit!

Shonky and awesome.
