Badger 2040

by Pimoroni

A hackable, programmable badge with E Ink® display, powered by Raspberry Pi RP2040.

In honour of Raspberry Pi's 10th birthday, we've fused a RP2040 microcontroller with an EPD display to produce a stylishly monochrome, maker friendly, e-paper badge(r) to attach to your person, your office door or to prop up on your desk.

We've equipped Badger 2040 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. On the back, you'll find some funky badgerpunk stylings plus our RP2040 accoutrements of choice: boot and reset buttons and a Qw/ST connector so it's super easy to plug in Qwiic or STEMMA QT breakouts

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.

RP2040 x e Ink®

We're big fans of electronic paper at Pirate HQ - it makes for a lovely, crisp, high contrast display that's readable even in bright sunlight and it doesn't squirt unnecessary blue light into your environs like LCDs do. It's also ultra low power (EPD displays only consume power while they're refreshing), and the images on the display stick around for a really long time whilst the display is unpowered.

Using a RP2040 chip means we can drive the hardware in fun, experimental, low level ways. We've written custom drivers for the EPD display that prioritise low power consumption whilst enabling lightning fast refresh rates.

Features

  • 2.9" black and white E Ink® display (296 x 128 pixels)
    • Ultra wide viewing angles
    • Ultra low power consumption
    • Dot pitch - 0.227 x 0.226 mm
  • Powered by RP2040 (Dual Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM)
  • 2MB of QSPI flash supporting XiP
  • Five front user buttons
  • Reset and boot buttons (the boot button can also be used as a user button)
  • White LED
  • USB-C connector for power and programming
  • JST-PH connector for attaching a battery (input range 2.7V - 6V)
  • High-precision voltage reference for battery level monitoring
  • Qw/ST (Qwiic/STEMMA QT) connector
  • Fully-assembled (no soldering required)
  • Schematic
  • Mechanical drawing
  • C++/MicroPython libraries

Badger + Accessory Kit includes

  • Badger 2040
  • 2 x AAA battery holder
  • 2 x AAA batteries
  • Velcro square
  • Black lanyard (made from recycled plastic bottles!)
  • USB-C to USB-A cable

Software

Because it's a RP2040 board, Badger 2040 is firmware agnostic! You can program it with C/C++, MicroPython or CircuitPython. We'd recommend using our batteries included MicroPython build for ease of getting started.

You can draw on the screen using our lightweight PicoGraphics library, which includes functions for displaying text, shapes and images (plus individual pixels of course), and we've provided some examples to get you started.

Badger ships pre-loaded with MicroPython and our BadgerOS suite of examples.

MicroPython

C/C++

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 our library, but you will get access to all the nice conveniences of Adafruit's ecosystem.

Connecting Breakouts

If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable, or you can easily connect any of our I2C Breakout Garden breakouts with a JST-SH to JST-SH cable coupled with a Qw/ST to Breakout Garden adaptor.

Notes

  • Measurements: 85.6mm x 48.7mm x 10mm (L x W x H, including connectors). The mounting holes are M2 and 2.9mm in from each edge. The corner radius is 3mm.
  • Badger 2040 is fairly accommodating about input voltage (2.7V - 6V), so it's possible to use a variety of different batteries and battery packs. A 2x AAA battery pack fits behind Badger nicely (double/triple AA and AAA battery packs will also work though).
  • 2x AAA rechargeable (NiMH) batteries only puts out 2.4V which is, strictly speaking, not enough for Badger. However, in our tests it keeps on truckin' down to an input voltage of 2.05V (without the LED), so if you want to use rechargeable batteries that should be fine.
  • Alternatively, you can plug a LiPo/LiIon battery into the battery connector, with the following caveats. Please only consider this if the person wearing the badge is an adult and knows what they're doing with LiPos!
    • A solid enclosure or backplate to protect the battery from damage whilst being worn is a very good idea (or you could use one of our Galleon hard case LiPo batteries).
    • There's no battery protection included on Badger 2040, so you should only use it with LiPo batteries that include internal protection (all ours do).
    • Unlike some of our other boards, Badger 2040 doesn't have battery charging circuitry onboard. You'll need an external LiPo charger to charge the battery (like a LiPo Amigo).
  • With older versions of the Badger firmware, reset behaviour is slightly different when running on battery. If you're running on battery power, you will need to tap the reset button on the back, and then hold any of the front buttons to wake it up and trigger a refresh. With version 1.18.5 or later of the Badger firmware you won't need to do this.
  • Never set your password as "mushroom". It is not stroganoff.

About RP2040

Raspberry Pi's RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.

One very exciting feature of RP2040 is the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.

It's a very nice little gaming console with a decent display and an aluminium case that looks and feels quite sturdy and durable. You can find some games for it on the internet - but the real fun could be writing those by yourself. When I tried I found a reason that makes me write this four-star-only rating. To access the debug pins of the built-in RP2040 you have to open and remove the case. It would have been much nicer if there was one removable panel with those pins behind...

Well built, feels very premium. There's a decent little community making games for it, and it can run things like an NES emulator without too much issue. I am not currently a skilled enough C++ developer to make anything worth playing for it, but I did manage some basics reasonably quickly.

I'm really impressed by what this tiny thing is able to do! I was able to write a simple game in a matter of hours... You can even upload a NES emulator on it.

An awesome system based on RP2040. Build quality is very solid and the device has a very nice weight to it. Battery life is also very good. Comes with a nice platformer pre-installed. I haven't made anything with it yet but look forward to adapting my Pico Display games to this one.

Very comfortable in hand. Seem sturdy enough to lend it to my small children. I am in the process of porting one of my web game to it. Very easy to program for it, or, if that's not your thing, to load the few available games on it.

System works well, instructions are good. I had issues with tool chain on windows for raspberry pico sdk. Once I switched to Debian in virtual box everything worked fine. I recommend using putty and ssh for programming to get copy paste functionality and winscp to copy files. The hardware is very well built and I highly recommend it.

It looks like a commercial games device, it looks really good. Solid build and I cannot wait to start building games and apps for it.

The build quality is extremely good. Especially the aluminium case makes it feel great. The screen has a good quality but it’s pretty small which kind of makes the charm of the PicoSystem. The 32blit SDK is great for developing own games and it has an active community behind it. There are also other SDKs available which I haven’t had experience with yet. Overall the PicoSystem is great for getting into retro game development.

A very cool little device. I love the metallic body and front plate.

Great little device! It feels super solid and high-quality, and looks fantastic. The RP2040 is very nice so far, and importantly, both the PicoSDK and the PicoSystem SDK are very easy to use, especially the examples in the PicoSystem repo. If you've dabbled in retro console game dev, the PicoSystem is something like a GBA packed into the size of a GB Micro, and has similar limitations in RAM and ROM, just with a smaller screen (but roughly twice the pixels of the original GB at 240x240 vs 160x144), same button count as the original GB, a much faster CPU, and MUCH better documentation. Highly recommend it; it's a lot of fun.
