IR: common questions

What microcontroller does the IR use?

The IR is built around the STM32G030K6T6, from the STM32 family.

How big is the IR PCB?

The IR measures 96 × 138 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IR?

190 components, from 40 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 design files?

From the Tomoshibi-technology/RCJ-Japan2024-Circuit 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 design in my own project?

Yes, under the terms of its MIT license, which Tomoshibi-technology chose for the repository.

Can I test firmware for the IR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
