Pneumatic ctrl: common questions
What microcontroller does the Pneumatic ctrl use?
The Pneumatic ctrl is built around the ATTINY3224-SS, from the AVR/Arduino family.
How big is the Pneumatic ctrl PCB?
The Pneumatic ctrl measures 60 × 86 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pneumatic ctrl?
58 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Pneumatic ctrl design files?
From the adarwoo/KiCad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Pneumatic ctrl design in my own project?
The repository has no license, so all rights stay with adarwoo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pneumatic ctrl 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.
