Uedaino: common questions
What microcontroller does the Uedaino use?
The Uedaino is built around the ATMEGA328P-A, from the AVR/Arduino family.
How big is the Uedaino PCB?
The Uedaino measures 50 × 65 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Uedaino?
30 components, from 25 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 Uedaino design files?
From the fabkominka/uedaino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Uedaino design in my own project?
The repository has no license, so all rights stay with fabkominka. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Uedaino 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.
