Image of Board

A hackable, programmable badge(r) with monochrome E Ink® display, powered by Raspberry Pi RP2040. It has a quintet of buttons (one for each claw), a slot so you can clip it onto a lanyard and a battery connector to keep things portable. You can even connect it up to Qwiic and STEMMA QT breakouts!

Features

  • 2.9” black and white E Ink® display (296 x 128 pixels)
  • 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 for breakouts

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.

CircuitPython 9.2.0-beta.1

This is the latest development release of CircuitPython that will work with the Badger 2040.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
