Plasma Pilot4: common questions
What microcontroller does the Plasma Pilot4 use?
The Plasma Pilot4 is built around the ATTINY861A-S, from the AVR/Arduino family.
How big is the Plasma Pilot4 PCB?
The Plasma Pilot4 measures 85.1 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Plasma Pilot4?
78 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the Plasma Pilot4 design files?
From the xdmattz/Plasma-Starter repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Plasma Pilot4 design in my own project?
The repository has no license, so all rights stay with xdmattz. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Plasma Pilot4 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.
