About the OpenEduBot PCB

OpenEduBot is an open source RP2040/RP2350 PCB design by shepai, published on GitHub. It is a 2-layer board measuring 77.1 × 89.2 mm, with 40 components from 24 distinct parts.

Its main chip is the PCA9685, from the RP2040/RP2350 family. Other key parts include the 4050D, AP2112K-3.3 and MPU-6050. By type, the board carries 13 resistors, 9 capacitors, 4 ICs, 3 diodes, 2 modules and 2 fuses.

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

From the project

Python library and robotics building instructions for robotics education within schools. The aim of this project is to provide ease of teaching and programming with MicroPython, and reduce the cost of teaching robotics

Once the library is installed on the device.

There are two variants of the library, a circuitPython and a microPython. The circuitPython can work with both the Pico and PiMaker rp2040. The microPython one is designed for the Raspberry Pi Pico.

OpenEduBot: common questions

What microcontroller does the OpenEduBot use?

The OpenEduBot is built around the PCA9685, from the RP2040/RP2350 family.

How big is the OpenEduBot PCB?

The OpenEduBot measures 77.1 × 89.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenEduBot?

40 components, from 24 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 OpenEduBot design files?

From the shepai/OpenEduBot 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 OpenEduBot design in my own project?

The repository has no license, so all rights stay with shepai. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the OpenEduBot 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.
