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!

## About the RP2040
34
-
The 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 the RP2040 microcontroller are 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.
