McuOpenPnP Machine: common questions
What microcontroller does the McuOpenPnP Machine use?
The McuOpenPnP Machine is built around the MK20DX128VFT, from the NXP family.
How big is the McuOpenPnP Machine PCB?
The McuOpenPnP Machine measures 3.5 × 2.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the McuOpenPnP Machine?
55 components, from 34 distinct parts. The full bill of materials is listed on this page.
Where can I download the McuOpenPnP Machine design files?
From the ErichStyger/McuOpenPnP_Machine repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the McuOpenPnP Machine design in my own project?
The repository has no license, so all rights stay with ErichStyger. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the McuOpenPnP Machine 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.
