Omschrijving
Badger 2040 is a hackable, programmable badge with E Ink display, powered by Raspberry Pi RP2040.
The Badger 2040 is equipped with plenty of buttons so you can easily change what's displayed on the screen, a slot so you can clip it onto a lanyard and a battery connector so you can keep things portable and refresh the screen whilst on the go.
Here are some things you could do with it!
- Switch between images, pronouns or secret identities at the push of a button
- Make yourself into a mobile weather station or air quality monitor (by adding a sensor breakout)
- Store important QR codes for getting into places (or to Rickroll people)
- Make a tiny to-do list and tick stuff off
- Display inspirational badger quotes or educational badger facts of the day
Want to show your Badger the world? We've put together a convenient Badger + Accessory Kit which contains batteries, a lanyard and everything else that's needed to get portabello.

Software
Because it's a RP2040 board, Badger 2040 is firmware agnostic! You can program it with C/C++, MicroPython or CircuitPython.
C++/MicroPython libraries contain some nifty software tweaks to let you get the most out of your Badger. You'll get best performance using C++, but if you're a beginner we'd recommend using our batteries included MicroPython build for ease of getting started.
You can also use CircuitPython on your Badger 2040. CircuitPython drivers are designed to work on a bunch of different microcontrollers so you won't get the fancy RP2040-architecture specific tweaks that you'll find in the library, but you will get access to all the nice conveniences of Adafruit's ecosystem.
