Zensai65 UNI i4: common questions

What microcontroller does the Zensai65 UNI i4 use?

The Zensai65 UNI i4 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Zensai65 UNI i4 PCB?

The Zensai65 UNI i4 measures 323.9 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zensai65 UNI i4?

178 components, from 21 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 Zensai65 UNI i4 design files?

From the shoonie-desu/zensai_pcb 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 Zensai65 UNI i4 design in my own project?

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

Can I test firmware for the Zensai65 UNI i4 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.
