Megaduino: common questions
What microcontroller does the Megaduino use?
The Megaduino is built around the Teensy3.2, from the NXP family.
How big is the Megaduino PCB?
The Megaduino measures 48.9 × 52.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Megaduino?
38 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Megaduino 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 Megaduino 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 Megaduino 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.
