DC-DC Board Micro: common questions

What microcontroller does the DC-DC Board Micro use?

The DC-DC Board Micro is built around the ATSAMD21E16L-MFT, from the Microchip SAM family.

How big is the DC-DC Board Micro?

The DC-DC Board Micro measures 58.4 × 36.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DC-DC Board Micro?

54 components, from 35 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 DC-DC Board Micro 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 DC-DC Board Micro 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 DC-DC Board Micro 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.
