RotarySwitch: common questions

What microcontroller does the RotarySwitch use?

The RotarySwitch is built around the PIC16F1847-IP, from the PIC family.

How big is the RotarySwitch PCB?

The RotarySwitch measures 78.7 × 92.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RotarySwitch?

154 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the RotarySwitch design files?

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

Can I use the RotarySwitch design in my own project?

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

Can I test firmware for the RotarySwitch without the hardware?

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