RC-Switch: common questions

What microcontroller does the RC-Switch use?

The RC-Switch is built around the ATtiny85-20P, from the AVR/Arduino family.

How big is the RC-Switch PCB?

The RC-Switch measures 55.3 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RC-Switch?

22 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the RC-Switch design files?

From the dirk-sth/RC-Switch repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RC-Switch design in my own project?

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

Can I test firmware for the RC-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.
