Panel: common questions

What microcontroller does the Panel use?

The Panel is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Panel PCB?

The Panel measures 52.1 × 121.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Panel?

50 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Panel design files?

From the ZeniteSolar/MT19 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Panel 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 Panel 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.
