About the Koreem board

Koreem board is an open source RP2040/RP2350 PCB design by koreem-ahmed, published on GitHub under the MIT license. It is a 2-layer board measuring 343.9 × 125.4 mm, with 261 components from 13 distinct parts.

Its main chip is the Raspberry_Pi_Pico, from the RP2040/RP2350 family. Other key parts include the ST1S12XX. By type, the board carries 88 LEDs, 84 switches, 84 diodes and 5 ICs.

It belongs with the displays & leds and keyboards designs in this gallery.

Koreem board: common questions

What microcontroller does the Koreem board use?

The Koreem board is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Koreem board?

The Koreem board measures 343.9 × 125.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Koreem board?

261 components, from 13 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 Koreem board design files?

From the koreem-ahmed/Koreem-board 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 Koreem board design in my own project?

Yes, under the terms of its MIT license, which koreem-ahmed chose for the repository.

Can I test firmware for the Koreem board 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.
