V2.2: common questions
What microcontroller does the V2.2 use?
The V2.2 is built around the Teensy3.2, from the NXP family.
How big is the V2.2 PCB?
The V2.2 measures 39.4 × 52.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the V2.2?
36 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the V2.2 design files?
From the brunob45/megaduino repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the V2.2 design in my own project?
The repository has no license, so all rights stay with brunob45. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the V2.2 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.
