UnIC: common questions

What microcontroller does the UnIC use?

The UnIC is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the UnIC PCB?

The UnIC measures 50 × 15.2 mm, has 4 copper layers and is 1 mm thick.

How many components are on the UnIC?

193 components, from 35 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 UnIC design files?

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

Can I use the UnIC design in my own project?

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

Can I test firmware for the UnIC without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
