PneuCNTRL2: common questions

What microcontroller does the PneuCNTRL2 use?

The PneuCNTRL2 is built around the Teensy3.2, from the NXP family.

How big is the PneuCNTRL2 PCB?

The PneuCNTRL2 measures 84.5 × 107.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PneuCNTRL2?

161 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the PneuCNTRL2 design files?

From the hnnswldschtz/pneuCNTRL2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PneuCNTRL2 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the PneuCNTRL2 without the hardware?

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