Connect a glorious, squishy, 4x4 rainbow-illuminated keypad to your Raspberry Pi Pico - perfect for making a custom USB input device! Pico RGB Keypad Base - PIM551
Scoring very highly in the Pimoroni "things on our desk that make people say ooo" rankings, RGB Keypad Base equips a Pico with an eye-catching 4x4 silicone keypad, fully loaded with addressable APA102 LEDs so that each key can be illuminated in any colour that your little unicorn heart desires. It's all mounted on a sturdy base with rubber feet to keep it nice and level, with a handily labelled landing area for your Pico. We've broken out the full set of Pico pins to make it easy to connect up other hardware as well.
Connect your Pico project to another computer via USB for a beautiful macro keypad or a tidy midi controller. RGB Keypad Base would also work well in any project that would benefit from having fancy light up buttons as inputs - a code protected door lock perhaps, a disco dance floor for your fingers or a Simon Says style game with which to taunt your friends.
A Raspberry Pi Pico is not included .
Your Pico will need to have male headers soldered to it (with the pins pointing downwards) to attach to our add-on boards.
Turn the larger board over, and attach the little rubber feet to the paw print spaces on the bottom. Flip it over again, and pop the silicone keypad over the buttons so the tabs fit into the holes. You can then slot the retainer plate over the top of the keys, matching up the key markings with those on the base board. You can install the retainer plate either way up, depending on whether you prefer it patterned or plain!
Poke the M2 bolts through the holes in the mounting plate (from the top) and screw on the nuts to keep all the layers sandwiched together. The bolts only need to be tightened up enough to keep the layers in place - if you find that the keys are hard to push or that the silicone layer is bulging out of the sides you might want to slacken them off a bit. The labels on the base will show you which way round to attach your Pico - just match up the USB port to the markings on the board.
The easiest way to get started is by downloading and copying our custom MicroPython uf2 to your Pico, it includes all the libraries you'll need to use our add-ons.
Alternatively, if you're interested in setting your RGB Keypad up as an easy to program macropad, midi controller or other USB input device, check out the PMK CircuitPython library!
About Raspberry Pi Pico
Raspberry Pi Pico is a flexible, low cost microcontroller development board from the folks at Raspberry Pi, based on their very own chip - the RP2040. It's easily programmable over USB with C/C++ or MicroPython, and ideal for using in all sorts of physical computing projects, devices and inventions - we're so excited to see what you make with it!
We've called our Pico-sized add-ons packs, as they're designed to attach to the back of your Pico as if it were wearing a very stylish backpack (or a miniature jet pack, if you prefer). We've also got Pico bases (larger add-on boards with a space to mount your Pico on top) and some other boards that let you do interesting hackerly things like using multiple packs at once.
