Infrared gun: common questions

What microcontroller does the Infrared gun use?

The Infrared gun is built around the STM32F103C8TX, from the STM32 family.

How big is the Infrared gun PCB?

The Infrared gun measures 36 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Infrared gun?

38 components, from 24 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 Infrared gun design files?

From the souptik-samanta/Infrared-gun 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 Infrared gun design in my own project?

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

Can I test firmware for the Infrared gun 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.
