Trhw: common questions

What microcontroller does the Trhw use?

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

How big is the Trhw PCB?

The Trhw measures 210 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Trhw?

55 components, from 28 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 Trhw design files?

From the nimitvijayvargee/trhw 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 Trhw design in my own project?

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

Can I test firmware for the Trhw 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.
