PurrEngine hardware: common questions
What microcontroller does the PurrEngine hardware use?
The PurrEngine hardware is built around the DEV-13736, from the NXP family.
How big is the PurrEngine hardware PCB?
The PurrEngine hardware measures 60.3 × 19.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PurrEngine hardware?
42 components, from 20 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 PurrEngine hardware design files?
From the RevFur/PurrEngine-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 PurrEngine hardware design in my own project?
The repository has no license, so all rights stay with RevFur. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PurrEngine hardware 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.
