		whiskers on Feb 28, 2023 \| parent \| context \| favorite \| on: The E-Ink Badge If you look at the back of the badger you'll see that we put a set of pads to solder to for GPIO! It also has a "Qw/ST" connector (STEMMA + Qwiic) that exposes an I2C bus so is ideal for adding sensors, or you could bash on an IO expander for a heap more pins!

Sensors don't fit my use case, but I can't believe I didn't notice those pads. I'll see if I can make them work.

I don't believe that SD cards can be interfaced with over i2c.

If I were you guys I would consider having a built in SD reader in version 2.0, as it would add a lot of value.

It should be possible with Badger 2040 W: https://github.com/pimoroni/badger2040/issues/3
