About the Hid controller PCB

Hid controller is an open source STM32 PCB design by elitetq, published on GitHub. It is a 4-layer board measuring 129.3 × 113.2 mm, with 72 components from 30 distinct parts.

Its main chip is the STM32F103C8TX, from the STM32 family. Other key parts include the RT9080-33GJ5 and 9032. By type, the board carries 28 resistors, 16 capacitors, 15 switches, 4 ICs, 4 diodes and 3 connectors.

From the project

Making a custom HID controller PCB for interfacing with operating systems like Windows to play games.

A custom USB gamepad built on an STM32F103 (KiCad PCB + firmware). It has two analog sticks, a D-pad, face buttons, bumpers, triggers and Start/Share, and shows up on the host as an Xbox 360-style wired controller.

Linux enumerates it fully. Windows only partly enumerates it so far and the workaround is to use xbox360ce as an emulator for XInput.

Hid controller: common questions

What microcontroller does the Hid controller use?

The Hid controller is built around the STM32F103C8TX, from the STM32 family.

How big is the Hid controller PCB?

The Hid controller measures 129.3 × 113.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hid controller?

72 components, from 30 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 Hid controller design files?

From the elitetq/hid-controller 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 Hid controller design in my own project?

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

Can I test firmware for the Hid controller 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.
