About the Master PCB

Master is an open source PIC PCB design by coloradocube, published on GitHub. It is a 2-layer board measuring 96 × 90 mm, with 76 components from 44 distinct parts.

Its main chip is the PIC18F27Q84-E/SP, from the PIC family. Other key parts include the TPS61022RWUR, INA3221AIRGVR, MAX77757JEFG435+, MAX17055EWL+T and ATA6560-GAQW-VAO. By type, the board carries 21 resistors, 20 capacitors, 7 ICs, 7 diodes, 4 connectors and 3 inductors.

From the project

DEPRECATED

Current poorly implemented and understood version controls:

-Let team know you are going to work on the kicad files

-Work on files from the cloned repository on your local computer

-Commit files with short description of your changes to your branch (fork?)

-Notify Dan, he will merge with main branch

-How will we use shared libraries without it being a pain in the ass

The KiCad project lives in the coloradocube/balloonsat-bus repository on GitHub; these links point at the commit this page was built from.

Master: common questions

What microcontroller does the Master use?

The Master is built around the PIC18F27Q84-E/SP, from the PIC family.

How big is the Master PCB?

The Master measures 96 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Master?

76 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Master design files?

From the coloradocube/balloonsat-bus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Master design in my own project?

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

Can I test firmware for the Master without the hardware?

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