Multi channel: common questions

What microcontroller does the Multi channel use?

The Multi channel is built around the ATMEGA328PB, from the AVR/Arduino family.

How big is the Multi channel PCB?

The Multi channel measures 80 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Multi channel?

37 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Multi channel design files?

From the LilyTronics/lily_kicad_lib repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Multi channel design in my own project?

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

Can I test firmware for the Multi channel 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.
