About the Revo main bottom PCB

Revo main bottom is an open source RP2040/RP2350 PCB design by ratmuds, published on GitHub under the MIT license. It is a 4-layer board measuring 100 × 30 mm, with 23 components from 19 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the MINI360 and THVD1420D. By type, the board carries 12 connectors, 5 resistors, 3 ICs, 2 capacitors and 1 module.

It belongs with the robotics & motion designs in this gallery.

Revo main bottom: common questions

What microcontroller does the Revo main bottom use?

The Revo main bottom is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Revo main bottom PCB?

The Revo main bottom measures 100 × 30 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Revo main bottom?

23 components, from 19 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 Revo main bottom design files?

From the ratmuds/revo 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 Revo main bottom design in my own project?

Yes, under the terms of its MIT license, which ratmuds chose for the repository.

Can I test firmware for the Revo main bottom 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.
