About the RICM pico PCB

RICM pico is an open source RP2040/RP2350 PCB design by elatorre20, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 203 × 88 mm, with 68 components from 16 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the PCA9555D. By type, the board carries 19 switches, 18 resistors, 11 capacitors, 9 diodes, 3 ICs and 2 connectors.

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

From the project

The software for a raspberry PIco-based kit board for a tic-tac-toe game. The board is mostly based on I2C devices, and will be simple to assemble so that we can use it in children's workshops. Written in micropython and C.

Developed at Rhode Island Computer Museum

RICM pico: common questions

What microcontroller does the RICM pico use?

The RICM pico is built around the Pico, from the RP2040/RP2350 family.

How big is the RICM pico PCB?

The RICM pico measures 203 × 88 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RICM pico?

68 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the RICM pico design files?

From the elatorre20/RICM_pico repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RICM pico design in my own project?

Yes, under the terms of its GPL-3.0 license, which elatorre20 chose for the repository.

Can I test firmware for the RICM pico 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.
