Uvw switch: common questions

What microcontroller does the Uvw switch use?

The Uvw switch is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Uvw switch PCB?

The Uvw switch measures 139.7 × 76.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Uvw switch?

61 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Uvw switch design files?

From the MIH-pi/uvw_switch repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Uvw switch design in my own project?

Yes, under the terms of its MIT license, which MIH-pi chose for the repository.

Can I test firmware for the Uvw switch 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.
