UNO-TH Rev3e: common questions

What microcontroller does the UNO-TH Rev3e use?

The UNO-TH Rev3e is built around the ATMEGA16U2-MU(R), from the AVR/Arduino family.

How big is the UNO-TH Rev3e PCB?

The UNO-TH Rev3e measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UNO-TH Rev3e?

111 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the UNO-TH Rev3e design files?

From the NadjB/Hard_Arduino_and_Shield repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the UNO-TH Rev3e design in my own project?

The repository has no license, so all rights stay with NadjB. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the UNO-TH Rev3e 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.
