Counter pneumatic v1: common questions

What microcontroller does the Counter pneumatic v1 use?

The Counter pneumatic v1 is built around the ATMEGA328-AU, from the AVR/Arduino family.

How big is the Counter pneumatic v1 PCB?

The Counter pneumatic v1 measures 91.4 × 116.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Counter pneumatic v1?

38 components, from 24 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 Counter pneumatic v1 design files?

From the jekhor/pneumatic-tc-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Counter pneumatic v1 design in my own project?

The repository has no license, so all rights stay with jekhor. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Counter pneumatic v1 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.
