About the Power carrier PCB

Power carrier is an open source Raspberry Pi PCB design by reubenstr, published on GitHub. It is a 2-layer board measuring 74 × 240 mm, with 24 components from 10 distinct parts.

Its main chip is the RASPBERRY_PI_4B - Footprint Only, from the Raspberry Pi family. Other key parts include the SCW12B-05. By type, the board carries 18 connectors, 1 IC, 1 switch, 1 diode and 1 resistor.

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

From the project

DIY 3D printed quadruped robot.

- Add voltage/current sensor such as a INA228 - Add revision number to silkscreen - Optional: Add motor tags (ex, FLA, FLH, FLK) to silkscreen - Move 5vDC terminal away from RPi as this blocks the power switch if a RPi 5 is used. - Some of the PCB may be removed to save weight, perhaps under the battery.

Power carrier: common questions

What microcontroller does the Power carrier use?

The Power carrier is built around the RASPBERRY_PI_4B - Footprint Only, from the Raspberry Pi family.

How big is the Power carrier PCB?

The Power carrier measures 74 × 240 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power carrier?

24 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Power carrier design files?

From the reubenstr/ElectroPup repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Power carrier design in my own project?

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

Can I test firmware for the Power carrier 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.
