About the Rp micro PCB

Rp micro is an open source RP2040/RP2350 PCB design by siderakb, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 17.8 × 33 mm, with 35 components from 17 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q64JVXGIQ and RT9013-33GB. By type, the board carries 16 capacitors, 9 resistors, 3 ICs, 2 switches, 1 crystal and 1 connector.

It belongs with the keyboards designs in this gallery.

From the project

Pro Micro/Elite-Pi compatible RP2040 board with USB-C, 8MB flash and up to 25 GPIOs

RP Micro is a Pro Micro compatible RP2040 board with USB Type-C and 8MB flash, inspired by the plut0nium/0xB2, joshajohnson/sea-picro and Elite-Pi, specialized design for keyboards.

Go to Releases for Gerber, schematic and PCBA files.

- SparkFun Pro Micro - RP2040 compatible pinout, with additional 5+2 pins (Elite-C and Elite-Pi style, but the pinout not identical to Elite-Pi). - RAW: LDO regulator VIN pin. - Blue LED LD1: State/User LED (Connect to GP25). - All the GPIO pins of RP2040 can be used as PWM output. - Select whether the 3rd and 4th pads in the left column are GND or GP10/GP11…

Rp micro: common questions

What microcontroller does the Rp micro use?

The Rp micro is built around the RP2040, from the RP2040/RP2350 family.

How big is the Rp micro PCB?

The Rp micro measures 17.8 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp micro?

35 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Rp micro design files?

From the siderakb/rp-micro repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Rp micro design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which siderakb chose for the repository.

Can I test firmware for the Rp micro without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
