Main Robot Board: common questions
What microcontroller does the Main Robot Board use?
The Main Robot Board is built around the PIC32MZ2048EFH144-I/PL, from the PIC family.
How big is the Main Robot Board?
The Main Robot Board measures 100 × 86.3 mm, has 4 copper layers and is 1.769872 mm thick.
How many components are on the Main Robot Board?
109 components, from 38 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 Main Robot Board design files?
From the satomm1/Robot 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 Main Robot Board design in my own project?
Yes, under the terms of its MIT license, which satomm1 chose for the repository.
Can I test firmware for the Main Robot Board 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.
