Pimoroni PIM561 Keybow 2040 Linear quiet 16-key development board

SKU CH-17SQ-ZD6G7

A compact 16-key development board with hot-swap mechanical switches, per-key RGB lighting and an RP2040 microcontroller for custom macros and input projects

  • RP2040 microcontroller powers fast, low-latency input
  • 16 low-profile keys in a 4×4 matrix connect directly to GPIOs
  • Kailh hot-swap sockets let you choose Cherry MX-compatible switches
  • Per-key RGB LEDs driven by IS31FL3731 PWM driver for custom lighting
  • USB-C provides power and programming in one compact board

16-key RP2040 development board

The Pimoroni Keybow 2040 is a compact 4×4 macro pad built around the Raspberry Pi RP2040 microcontroller. It suits makers, developers and streamers who need a programmable keypad with per-key lighting for shortcuts, macros or custom input experiments.

Hot-swap Kailh sockets with IS31FL3731 RGB driver

Low-profile linear switches come pre-installed in hot-swap Kailh sockets, so you can replace them with any Cherry MX-compatible switch without soldering. Each key has an addressable RGB LED driven by an IS31FL3731 PWM matrix driver, and the board includes dedicated BOOTSEL and reset buttons for easy firmware updates.

USB-C power and 2 MB flash

The board draws power and communicates over a single USB-C connection and provides 2 MB of onboard flash for CircuitPython or MicroPython scripts. Check that your host can supply enough current for 16 illuminated keys and that your enclosure can accommodate the 4×4 key matrix and low-profile switch height.

Questions about this item

What does the USB-C interface on the Keybow 2040 allow you to do?

The USB-C port powers the board and provides the data connection for programming the RP2040 microcontroller.

What physical space and mounting does the 4x4 key matrix require?

The board measures a compact 4x4 grid with low-profile Kailh hot-swap sockets and transparent DSA keycaps; four corner mounting holes secure it inside a case.

How do you put the RP2040 into bootloader mode for the first firmware flash?

Hold the BOOTSEL button while plugging the USB-C cable in; the board then appears as a mass-storage device so you can drag a UF2 file onto it.
