About the RTShield PCB

RTShield is an open source RP2040/RP2350 PCB design by o7-machinehum, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 89 × 61 mm, with 87 components from 41 distinct parts.

Its main chip is the RP2350B, from the RP2040/RP2350 family. Other key parts include the W25Q32JVSSIQ, NUP2202W1T2G, LM4040C33FTA, LM66100DCKR and AOZ1280CI. By type, the board carries 30 capacitors, 22 resistors, 10 connectors, 9 ICs, 6 diodes and 3 switches.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Breakout board for a RPi.

Basically... If you make boards for yourself: great, make boards for your friends: great, but please do not sell hundreds on them on Aliexpress.

The KiCad project lives in the o7-machinehum/RTShield repository on GitHub; these links point at the commit this page was built from.

RTShield: common questions

What microcontroller does the RTShield use?

The RTShield is built around the RP2350B, from the RP2040/RP2350 family.

How big is the RTShield PCB?

The RTShield measures 89 × 61 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RTShield?

87 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the RTShield design files?

From the o7-machinehum/RTShield repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RTShield design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the RTShield 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.
