MSWI19: common questions

What microcontroller does the MSWI19 use?

The MSWI19 is built around the ATmega328PB-AU, from the AVR/Arduino family.

How big is the MSWI19 PCB?

The MSWI19 measures 140 × 72.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MSWI19?

147 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the MSWI19 design files?

From the ZeniteSolar/MSWI19 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MSWI19 design in my own project?

Yes, under the terms of its GPL-3.0 license, which ZeniteSolar chose for the repository.

Can I test firmware for the MSWI19 without the hardware?

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