Motherboard: common questions

What microcontroller does the Motherboard use?

The Motherboard is built around the EFM32ZG108F32-QFN24, from the Silicon Labs family.

How big is the Motherboard PCB?

The Motherboard measures 50.8 × 20.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Motherboard?

21 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Motherboard design files?

From the HashDefineElectronics/HDEC-000745 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Motherboard design in my own project?

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

Can I test firmware for the Motherboard without the hardware?

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