About the Head rifle round sensors PCB

Head rifle round sensors is an open source STM32 PCB design by DAlexis, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 90.4 × 95.5 mm, with 61 components from 32 distinct parts.

Its main chip is the STM32F103RE, from the STM32 family. Other key parts include the USBLC6-4 and MCP73831. By type, the board carries 17 resistors, 13 connectors, 12 capacitors, 8 transistors, 4 ICs and 2 relays.

It belongs with the iot & wireless and sensors designs in this gallery.

From the project

Caustic project is a full-featured indoor and outdoor lasertag system

Caustic Lasertag System licensed under GPLv3. Third party code used in project may be licensed under other licences, see corresponding files and comments in the sources. Copyright 2016, see AUTHORS file.

You need to install cmake, arm-none-eabi-gcc compiler with arm-none-eabi-newlib and arm-none-eabi-binutils installed, and installation dirs should be in $PATH. Simply installation from your distro's repository usually enough. To flash the MCU with ST-link programmer you should install stlink utility. Then:

Head rifle round sensors: common questions

What microcontroller does the Head rifle round sensors use?

The Head rifle round sensors is built around the STM32F103RE, from the STM32 family.

How big is the Head rifle round sensors PCB?

The Head rifle round sensors measures 90.4 × 95.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Head rifle round sensors?

61 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Head rifle round sensors design files?

From the DAlexis/caustic-lasertag-system repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Head rifle round sensors design in my own project?

Yes, under the terms of its GPL-3.0 license, which DAlexis chose for the repository.

Can I test firmware for the Head rifle round sensors 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.
