About the Power-Testing-Board

Power-Testing-Board is an open source AVR/Arduino PCB design by MatthewBasha, published on GitHub. It is a 4-layer board measuring 230 × 170 mm, with 67 components from 46 distinct parts.

Its main chip is the Arduino Nano USB-powered socket, from the AVR/Arduino family. Other key parts include the CUSTOMER_SUPPLIED_OR_VERIFY_LCSC, INA260 3V3 module, INA260 5V module, INA260 12V module and INA260 16V8 module. By type, the board carries 34 resistors, 9 ICs, 8 capacitors, 5 transistors, 4 connectors and 4 switches.

From the project

This is a power testing board for CSULB's Sharksat

Compact CubeSat EPS ground power-test board for ATX/boost-supplied rails.

- Root KiCad project: Power Testing board.kicadpro - Schematic was regenerated first in Power Testing board.kicadsch. - Serviceable PCB placement was generated in Power Testing board.kicadpcb. - Board outline is 230 mm x 170 mm. - PCB is routed as a 4-layer board with outer-layer routing, rail-specific copper zones, a solid In1.Cu GND reference plane, and final JLCPCB fabrication outputs in fabrication/JLCPCB/`.

Power-Testing-Board: common questions

What microcontroller does the Power-Testing-Board use?

The Power-Testing-Board is built around the Arduino Nano USB-powered socket, from the AVR/Arduino family.

How big is the Power-Testing-Board?

The Power-Testing-Board measures 230 × 170 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Power-Testing-Board?

67 components, from 46 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 Power-Testing-Board design files?

From the MatthewBasha/Power-Testing-Board 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 Power-Testing-Board design in my own project?

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

Can I test firmware for the Power-Testing-Board 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.
