About the PowerBrigand PCB

PowerBrigand is an open source AVR/Arduino PCB design by schenkzoola, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 90 × 100 mm, with 42 components from 22 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. By type, the board carries 15 resistors, 7 connectors, 5 switches, 4 fuses, 4 diodes and 2 transistors.

It belongs with the power & battery and displays & leds designs in this gallery.

From the project

A kit that allows you to build a high power 12v supply from a surplus HP server power supply.

Well, you can build one yourself from the source files here, or better yet, you can join the waitlist for a kit from my Tindie store below: https://www.tindie.com/products/schenktronics/power-brigand/ The parts for the first batch of kits have been ordered!

Power Brigand is a module that attaches to HP common slot power supplies that are normally used in servers. It has connectors and/or binding posts to bring 12v power to your devices. It also has controls which allow you to turn the power supply on and off, as well as display parameters such as voltage, current, and temperature from the…

PowerBrigand: common questions

What microcontroller does the PowerBrigand use?

The PowerBrigand is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the PowerBrigand PCB?

The PowerBrigand measures 90 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PowerBrigand?

42 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the PowerBrigand design files?

From the schenkzoola/PowerBrigand repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PowerBrigand 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 PowerBrigand without the hardware?

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