About the The-Breadboard-Plus PCB

The-Breadboard-Plus is an open source RP2040/RP2350 PCB design by NoxAevi, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 65.5 × 62.7 mm, with 36 components from 17 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the USBLC6-2SC6, NCP1117-1.5_SOT223, W25Q128JVS and ESP32-C3-WROOM-02. By type, the board carries 18 capacitors, 7 resistors, 5 ICs, 3 connectors, 2 switches and 1 crystal.

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

From the project

Breadboard, but microcontroller

- To be able to flash the ESP32-C3 on the board, you must use the code given in the firmware production folder. Raw code is given in this folder as well, and in order to build it, you would have to clone this repo for a PIO USB UART bridge by GrechTech and replace the uart-bridge.c file with the code version you want, bootloader for installing something like micropython, and the normal version for using thonny with micropython.

The-Breadboard-Plus: common questions

What microcontroller does the The-Breadboard-Plus use?

The The-Breadboard-Plus is built around the RP2040, from the RP2040/RP2350 family.

How big is the The-Breadboard-Plus PCB?

The The-Breadboard-Plus measures 65.5 × 62.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the The-Breadboard-Plus?

36 components, from 17 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 The-Breadboard-Plus design files?

From the NoxAevi/The-Breadboard-Plus 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 The-Breadboard-Plus design in my own project?

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

Can I test firmware for the The-Breadboard-Plus 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.
