Ir transmitter: common questions

What microcontroller does the Ir transmitter use?

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

How big is the Ir transmitter PCB?

The Ir transmitter measures 114.3 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ir transmitter?

81 components, from 43 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 Ir transmitter design files?

From the adeboni/electronics 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 Ir transmitter design in my own project?

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

Can I test firmware for the Ir transmitter 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.
