Developed by the QMK collaborators, the Proton C allows you to upgrade any Pro Micro compatible keyboard kit to take advantage of a robust USB Type-C port, a faster Arm chipset, and an optional speaker. Extra pins are availble on the lower half of the Proton C, and can be broken off for builds that aren't compatible.
Includes a 5V step-up output for WS2812 LED chains (rest of board is 3.3V), and a reset button to put the MCU into the bootloader mode.
* Through-hole mounted USB-C Port
* 32-bit 72Mhz Cortex-M4 processor (STM32F303CCT6)
* I2C, SPI, PWM, DMA, DAC, USART, I2S
* 23x 3.3V I/O Ports
* 1x 5V output for WS2812 LED chains
* 256Kb Flash
* 40Kb RAM
* AST1109MLTRQ speaker footprint
Estimated ship date: November 26th, 2018
The Keyboard Controller You Didn’t Know You Needed
At the heart of every keyboard is a controller. It is a computer chip that is responsible for translating your button presses into signals your computer can understand. Many PCB’s have a controller built in (or “Pre-soldered”) while others rely on an external controller. The most popular external controller is a Pro-Micro.
Jack Humbert and Clueboard have been working an improved controller. They call it Proton C and it is a drop-in replacement for a Pro-Micro, with some extra features:
USB-C Port that won’t break off easily
32-bit Cortex-M4 Processor
PWM on every exposed pin
A break-away section with extra pins and a place to mount a speaker
RESET button with a sane bootloader
Add Audio To Your Build
Proton C comes with a speaker mount you can use to add Audio to any build. Just solder in a Mallory Sonalert AST1109MLTRQ and you can have auditory feedback. Whether you play a sound for layer changes, use Music Mode to turn your keyboard into a piano, enable Audio Click, or just use it as a cute little soundboard, having the ability to play sounds will give you new ways to extend and customize your keyboard.
Upgrade Your Existing Pro-Micro Based Kit
You can solder a Proton C into any QMK-compatible kit that currently uses a Pro-Micro, and compile Proton C firmware without any extra work! We’ve done the heavy lifting of making your existing keyboards work without any keymap changes. Just adjust your make target and it will build an ARM firmware instead of an AVR firmware. Configurator support is coming in Q1 2019.
Take Your Handwired Build To The Next Level
Now you can have USB-C and Audio in your hand-wired builds! Proton C provides you with 23 GPIO pins to use- Enough to wire a full sized keyboard! If you’ve been thinking about building a custom keyboard the time has never been more right.
