DIYduino: common questions
What microcontroller does the DIYduino use?
The DIYduino is built around the ATmega32U4-AU, from the AVR/Arduino family.
How big is the DIYduino PCB?
The DIYduino measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DIYduino?
35 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the DIYduino design files?
From the szdiy/DIYduino repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DIYduino design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which szdiy chose for the repository.
Can I test firmware for the DIYduino without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
