RP2040-Breakout-Board: common questions

What microcontroller does the RP2040-Breakout-Board use?

The RP2040-Breakout-Board is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040-Breakout-Board?

The RP2040-Breakout-Board measures 15.2 × 30.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2040-Breakout-Board?

32 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP2040-Breakout-Board design files?

From the EPSILON0-dev/RP2040-Breakout-Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP2040-Breakout-Board design in my own project?

Yes, under the terms of its MIT license, which EPSILON0-dev chose for the repository.

Can I test firmware for the RP2040-Breakout-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.
