About the Mechanics PCB

Mechanics is an open source RP2040/RP2350 PCB design by cclienti, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 110 × 75 mm, with 81 components from 21 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the 24LC1025, LM2575-5.0BT and LM3940. By type, the board carries 27 resistors, 21 connectors, 15 capacitors, 10 transistors, 4 ICs and 2 diodes.

Mechanics: common questions

What microcontroller does the Mechanics use?

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

How big is the Mechanics PCB?

The Mechanics measures 110 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mechanics?

81 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mechanics design files?

From the cclienti/mechanics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mechanics design in my own project?

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

Can I test firmware for the Mechanics 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.
