UNOvx: common questions
What microcontroller does the UNOvx use?
The UNOvx is built around the ATmega328P-PU, from the AVR/Arduino family.
How big is the UNOvx PCB?
The UNOvx measures 72 × 54 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the UNOvx?
37 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the UNOvx design files?
From the bitomaxsp/UNOvx repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the UNOvx design in my own project?
Yes, under the terms of its MIT license, which bitomaxsp chose for the repository.
Can I test firmware for the UNOvx 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.
