Keybow 2040

by Pimoroni

Image of Board

A luxe 16 key USB-C keyboard with tactile mechanical switches and fully customisable RGB lighting, ideal for custom macro pads, midi controllers and stream decks. RP2040 gives Keybow 2040 low latency input, zero boot time and a new, compact footprint.


  • 16 (4x4 matrix) of low profile keys connected directly to GPIOs
  • Per key RGB LEDs driven by an IS31FL3731 PWM LED matrix driver
  • Kailh hot-swap switch sockets (for Cherry MX-compatible switches)
  • Powered and programmable via USB-C

About the RP2040

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.

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
