Gamepad hardware: common questions

What microcontroller does the Gamepad hardware use?

The Gamepad hardware is built around the STM32F070F6Px, from the STM32 family.

How big is the Gamepad hardware PCB?

The Gamepad hardware measures 100 × 50 mm, has 4 copper layers and is 1.58 mm thick.

How many components are on the Gamepad hardware?

44 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gamepad hardware design files?

From the isobchuk/gamepad_hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gamepad hardware design in my own project?

Yes, under the terms of its Apache-2.0 license, which isobchuk chose for the repository.

Can I test firmware for the Gamepad hardware 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.
