MWGEN-G1: common questions
What microcontroller does the MWGEN-G1 use?
The MWGEN-G1 is built around the EFM32PG22C200F512IM40, from the Silicon Labs family.
How big is the MWGEN-G1 PCB?
The MWGEN-G1 measures 100 × 100 mm, has 4 copper layers and is 1.59 mm thick.
How many components are on the MWGEN-G1?
341 components, from 84 distinct parts. The full bill of materials is listed on this page.
Where can I download the MWGEN-G1 design files?
From the MR-DOS/MWGEN-G1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MWGEN-G1 design in my own project?
Yes, under the terms of its GPL-3.0 license, which MR-DOS chose for the repository.
Can I test firmware for the MWGEN-G1 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.
