Description
Product information "Adafruit MACROPAD RP2040, 3x4 Keys + Encoder + OLED, Bare Bones"
That's just the bare MACROPAD board! Many people in the mechanical keyboard community want to customise the keys and keycaps to their requirements, so this product is sold here as "bare bones". To use it as a full-fledged product, you'll need to add 12 MX-compatible keyswitches and matching keycaps.
Get ready to upgrade the mission control station on your desk with a CircuitPython or Arduino-controlled Macropad - complete with 12 buttons, OLED display, speaker and rotary encoder. Customise it to your spaceship to guide you through the vastness of the unknown. (Or just let it type your favourite emojis.)
Each of the 12 sockets can accommodate a Cherry MX-compatible key switch. No soldering required, just snap in! You can use any MX button you like - but we recommend ones designed for LEDs, through which the matching twelve NeoPixels below can shine.
This spaceship is also equipped with a 128x64 monochrome OLED display, which is a crisp heads-up display that can be used in Arduino or CircuitPython to show button assignments, stats, computer performance, and more. A rotary encoder with push button is also soldered in. By turning or pressing it, you can change the volume, the brightness of the screen or the scrolling - just as you like! A tiny speaker can provide audio feedback or play funny beeps.
Want to add more hardware? No problem - the STEMMA QT connector on the side lets you connect any I2C add-on devices from the extensive STEMMA QT / Qwiic family of plugin boards.
Please note that the RP2040 chip currently has no QMK support - this Macropad is designed for programming with Arduino or CircuitPython! When QMK adds the RP2040 as a supported chipset (we don't know when that will happen and have no plans), we will update this page.
- Raspberry Pi RP2040 chip + 8MB flash memory - dual-core Cortex M0+ with ~130MHz and 264KB or RAM. Runs smoothly with CircuitPython, Arduino or MicroPython and provides plenty of space for development code and files
- USB-C connector for power/data - this can of course function as an HID device, but also as MIDI, UART, etc.
- 3x4 mechanical key sockets - for all Cherry MX compatible switches. Individually bound to GPIO pins (not matrix wired)
- One NeoPixel RGB LED per button, on the north side
- Rotary encoder, 20 clicks per revolution, with pushbutton switch on GPIO pin. The push switch is also used to enter bootloader mode when held down during power up or reset.
- 128x64 SH1106 monochrome OLED display - With high-speed hardware SPI port for fast updates
- 8 mm speaker/buzzer - With Class D amplifier and RC filter, can be used for simple beeps and sound effects.
- STEMMA QT connector - Allows you to add any I2C sensors/displays/devices with plug-and-play cables.
- Reset button - On the side, for a quick restart of the code
- Four M3 mounting sockets - for easy production of customised housings

Adafruit: The expert for open source hardware
For more than ten years, programmers and tinkerers have benefited from the expertise of the Adafruit brand. Whether for beginners or proven experts, Adafruit has the right hardware components ready for your next IoT project.
Light comes into the dark with Adafruit NeoPixel
One extremely popular product line from the company's broad portfolio is Adafruit NeoPixel. These nifty LED components come in a wide variety of designs and color temperatures. NeoPixel modules are available, for example, in the form of a practical stick with five intelligent LEDs in red, green and blue (RGB) or in white (W), as a shield with 40 eye-saving RGBW LEDs in which all pixels are individually addressable, and as a jewel with seven RGBW LEDs that can be controlled with 8-bit PWM per channel.
Especially popular is the Adafruit NeoPixel Ring with 16 ultra-bright, intelligent RGB LEDs including integrated drivers, which you only need a single microcontroller to control. The trick is that the Adafruit NeoPixel rings form a chain, so to speak: You couple the output pin of one with the input pin of the other.
With the Adafruit NeoPixel products you can realize a wide variety of projects - there are virtually no limits to your creativity. With the help of an Arduino, a jumper cable and the appropriate software, you can control a NeoPixel ring individually and light up the small LEDs as you wish - either individually or in a specific combination. This way, you can also create your own Vu meter with the versatile LED components. Practical: To make programming Adafruit NeoPixel easier, Adafruit provides an Arduino library as well as a Python library.
Adafruit Feather Boards: Powerful hardware in a compact format
With Adafruit Feather, the hardware specialist from the States also has various powerful development boards in its range, which are essentially equivalent to an Arduino in terms of function. All of these boards are equipped with similar features; among other things, the pin assignment is the same and there are also many parallels when it comes to the microcontrollers and the battery charging properties. In addition, you can also find Feather boards with special devices like Bluetooth, Wi-Fi and cellular network connectivity as well as boards with microSD slot in Adafruit's product range. The name "Feather" is no coincidence: The boards are also characterized by being particularly compact and, above all, lightweight.
The range of top-class product highlights is wide: The STM32F405 Feather, for example, is the fastest CircuitPython board from Adafruit with an outstanding 168 MHz and meets the highest demands. It is equipped with a STEMMA QT / Qwiic port at the end, which makes it easy to connect to I2C sensors. The Adafruit Feather nRF52840 Express, on the other hand, shines with Bluetooth Low Energy and can also be used with CircuitPython thanks to native USB support.
Another important part of Adafruit's portfolio are the FeatherWings. With these expansion modules, you can also include components such as a display or a motor driver in your IoT project. The FeatherWing Proto is a proven classic in Adafruit's portfolio. This is ideally suited as a prototyping add-on for all Feather boards. The Adafruit FeatherWing Wing Tripler Mini Kit, on the other hand, is ideal if you want to connect a Feather to two other FeatherWings at the same time.
With the Adafruit MIDI FeatherWing Kit you get a music capable FeatherWing, thanks to which you can equip your Feather with MIDI input and output jacks. And with the Adafruit FeatherWing OLED you can easily add a small OLED display to your Feather board - no soldering required.
Adafruit: What's behind the brand
As an expert in open-source hardware, Adafruit has long since established itself in the electronics industry. The company was founded in 2005 by Limor Fried. At the time, the talented and innovative electrical engineer was still a student at the renowned Massachusetts Institute of Technology (MIT). To this day, Fried is CEO of the electronics giant, which is now headquartered in New York. The company's name also goes back to its founder: Fried was once known on the World Wide Web by the nickname "Ladyada" - a tribute to the famous IT pioneer Ada Lovelace.
Adafruit says it is committed to getting more people excited about technology and science - and thanks to its first-class products, the hardware expert from the USA is sure to succeed!
