About the PCBA Board

PCBA Board is an open source Raspberry Pi PCB design by LukeZhang0826, published on GitHub. It is a 2-layer board measuring 52 × 57.9 mm, with 33 components from 29 distinct parts.

Its main chip is the C42394205, from the Raspberry Pi family. Other key parts include the DRV8833RTY and TPS54331. By type, the board carries 12 capacitors, 7 connectors, 7 resistors, 2 ICs, 2 transistors and 1 module.

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

From the project

Autonomous line-following rescue robot built for a competition at Waterloo's IDEAS Clinic. Raspberry Pi Pico and Arduino Mega, Pixy2 vision, custom KiCad PCBs.

An autonomous line-following rescue robot, built for a competition at the University of Waterloo's IDEAS Clinic. It follows a track, finds a coloured target, picks it up with a servo claw, carries it to a safe zone, drops it, then finds the line again and drives back.

We called it Hamster, which is why the robot code lives in Hamster/.

Built by Josh Lobe, Koketso Gaborekwe, Luke Zhang, Winters Xia, and Griffin Wilson.

PCBA Board: common questions

What microcontroller does the PCBA Board use?

The PCBA Board is built around the C42394205, from the Raspberry Pi family.

How big is the PCBA Board?

The PCBA Board measures 52 × 57.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCBA Board?

33 components, from 29 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 PCBA Board design files?

From the LukeZhang0826/RescueRobot 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 PCBA Board design in my own project?

The repository has no license, so all rights stay with LukeZhang0826. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCBA Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
