Evilia boat servo: common questions

What microcontroller does the Evilia boat servo use?

The Evilia boat servo is built around the PIC18F16Q41, from the PIC family.

How big is the Evilia boat servo PCB?

The Evilia boat servo measures 85 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Evilia boat servo?

73 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Evilia boat servo design files?

From the robperkel/evilia-boat-servo repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Evilia boat servo design in my own project?

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

Can I test firmware for the Evilia boat servo 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.
