Transparent one: common questions

What microcontroller does the Transparent one use?

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

How big is the Transparent one PCB?

The Transparent one measures 275 × 200 mm, has 2 copper layers and is 0.236 mm thick.

How many components are on the Transparent one?

79 components, from 25 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 Transparent one design files?

From the ItsShadowCone/tmfl 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 Transparent one design in my own project?

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

Can I test firmware for the Transparent one 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.
