OMiGaS: common questions

What microcontroller does the OMiGaS use?

The OMiGaS is built around the SparkFun Pro Micro - RP2040, from the RP2040/RP2350 family.

How big is the OMiGaS PCB?

The OMiGaS measures 92 × 44 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the OMiGaS?

120 components, from 59 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 OMiGaS design files?

From the XiaotianGuan/OMiGaS_KiCAD 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 OMiGaS design in my own project?

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

Can I test firmware for the OMiGaS 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.
