A new Class M planet called MACROPAD!\u003c\/p\u003e\n\u003cp\u003eM here, stands for Microcontroller because this 3x4 keyboard controller features the newest technology from the Raspberry Pi sector: say hello to the RP2040. It's a speedy little microcontroller with lots of GPIO pins and 64 times more RAM than the Apollo Guidance Computer. Adafruit added 8 MB of flash memory for plenty of storage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is just the bare MACROPAD PCB assembly!\u003c\/strong\u003e Many folks in the mechanical keyboard community like to customize the keys and keycaps of their keebs, so this is sold 'bare bones' here. \u003cstrong\u003eTo use as a full product you'll need to add 12 MX-compatible key switches and matching keycaps.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGet ready to upgrade your desk's mission control station with a CircuitPython or Arduino-powered Macropad - complete with 12 buttons, OLED display, speaker, and rotary encoder. Customize it for your spacecraft to help guide you through the great reaches of the unknown. (Or just have it type out your favorite emojis.)\u003c\/p\u003e\n\u003cp\u003eEach of the 12 sockets can accept a Cherry MX-compatible key switch. No soldering required, just snap it in! Use any key switch you like - but we recommend ones with slots that will allow the matching twelve NeoPixels underneath to shine through.\u003c\/p\u003e\n\u003cp\u003eThis spaceship is also fitted with a 128x64 monochrome OLED for a crisp heads-up display that can be used in Arduino or CircuitPython to display keymaps, stats, computer performance, etc. There's also a rotary encoder with push-button soldered in. Twist and turn it or push to change volume or monitor brightness or scroll: whatever you like! A tiny speaker can give audio feedback or play fun bleepy tunes.\u003c\/p\u003e\n\u003cp\u003eWant to add more hardware?
