Keybow 2040 by Pimoroni
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.
Features
- 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.

CircuitPython 10.0.0-alpha.2
This is the latest development release of CircuitPython that will work with the Keybow 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.
