Power Distribution Board: common questions

What microcontroller does the Power Distribution Board use?

The Power Distribution Board is built around the ATSAMD21E16L-MFT, from the Microchip SAM family.

How big is the Power Distribution Board?

The Power Distribution Board measures 60 × 85 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power Distribution Board?

106 components, from 21 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 Distribution Board design files?

From the EasternEdgeRobotics/Electrical_2019 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Power Distribution Board design in my own project?

Yes, under the terms of its MIT license, which EasternEdgeRobotics chose for the repository.

Can I test firmware for the Power Distribution Board without the hardware?

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