Description
Meet Helios, the RP2040 Controller with Pro Micro/Puchi-C/Elite-C compatible pinout, 16MB (128Mbit) of flash, Dual ARM Cortex-M0 @133MHz, and 264kB SRAM.
- ESD protection chip onboard
- Supports VBUS detection for split keyboards
- You can select VBUS instead of raw for the 5V pin to hook up an external USB port with the included D+ and D- pads while maintaining ESD protection.
- A default off red power LED that can be turn on via a jumper
- Blue user LED
- Level-shifter to drive 5V components
- Single button reset circuit which enables you to reset the board with a short click
- Enter the bootloader with a long (>500ms) click
- Open-source by 0xCB
The Helios comes without header pins, to keep the price low as possible.
I highly reccommend to use the "Single Row Sockets" from Mill-Max, the cheaper alternative, or the "Spring-loaded pin headers".
You can find the standard pin header here.
Example to compile the QMK firmware for the Helios (uf2 file, not hex).qmk compile -kb crkbd/rev1 -km via -e CONVERT_TO=helios

Sockets does not include the Pins. These can be ordered separately from the Drop-Down Menu. Sockets 1x QTY includes 2pcs socket headers (for a Split-Keyboard you need 2x QTY (4pcs socket headers)) Pitch: 0.100" (2.54mm) Contact Finish: Gold Instead of the pins, you can use legs from diodes/resistors, or these needle pins. Pins Length: 0.250" (6.35mm) Diameter: 0.020" (0.51mm) Example how to use the sockets.
Cheaper alternative to the Mill-Max Series 315 sockets 1 Qty = 1 socket row with 40x pin holes Easy split to needed length with a flush cutter Pitch: 0.100" (2.54mm) Both variants work with the Mill-Max 315 pins, but looser than with the Mill-Max sockets (with 7mm even more loose) Variants: Height 3mm Accepted diameter for pins: Variant 0.4mm < 0.7mm Not compatible with standard squared pins Compatible with this needle pins Height 7mm Accepted diameter for pins: Variant 0.6mm < 1.0mm Compatible with standard squared pins Compatible with this needle pins
12 pin per header H: 2.5mm (The dimension H is the distance between the PC boards) Rated current: 1A Rated voltage: 125V AC, DC Pitch: 2.54 mm includes 2x 12 pin header Insertion / removal forces (per pin): Through holeInsertion forcesRemoval forces 0.8 200g or less 50g or ove 0.85 150g or less 30g or ove 0.9 100g or less 20g or ove
This header pins can be soldered direct on the PCB, or you can use the "Single Row Socket Headers 2.54 Pitch (7mm)" to make it hotswap able.

The SparkFun Pro Micro RP2040 is a low-cost, high performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the good 'ol Pro Micro footprint, the board also includes a WS2812B addressable LED, boot button, reset button, Qwiic connector, USB-C, resettable PTC fuse, and castellated pads. The RP2040 utilizes dual ARM Cortex-M0+ processors (up to 133MHz) and features: 264kB of embedded SRAM in six banks Six dedicated IO for SPI Flash (supporting XIP) 30 multifunction GPIO Dedicated hardware for commonly used peripherals Programmable IO for extended peripheral support Four channel ADC with internal temperature sensor, 0.5 MSa/s, 12-bit conversion USB 1.1 Host/Device The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. The built-in USB can act as both device and host. It has two symmetric cores and high internal bandwidth, making it useful for signal processing and video. While the chip has a large amount of internal RAM, the board includes an additional 16MB external QSPI flash chip to store program code. Features RP2040 General Features Dual Cortex M0+ processors, up to 133 MHz 264 kB of embedded SRAM in 6 banks 6 dedicated IO for QSPI flash, supporting execute in place (XIP) 30 programmable IO for extended peripheral support SWD interface Timer with 4 alarms Real time counter (RTC) USB 1.1 Host/Device functionality Supported programming languages MicroPython C/C++ SparkFun Pro Micro - RP2040 Features Raspberry Pi Foundation's RP2040 microcontroller AP2112 3.3V voltage regulator Support programming languages MicroPython C/C++ On-board USB-C connector for programming USB 1.1 Host/Device functionality Built-in Resettable PTC Fuse PTH pads w/ castellated edges 20x multifunctional GPIO Pins [1] 4x 12-bit ADC channels with internal temperature sensor, 0.5 MSa/s, 12-bit 10x PWM channels Serial Peripherals 2x UARTs 1x I2C (Qwiic enabled) 1x SPI Buttons Boot Reset LEDs Power WS2812 Addressable LED 16MB External Flash Memory Dimensions: 1.3in x 0.7in [1] Note: The GPIO pins are muxed so you can reconfigure the pins for the digital interface of your choice!
