About the DPedal legacy PCB

DPedal legacy is an open source STM32 PCB design by rukai, published on GitHub under the MIT license. It is a 2-layer board measuring 154 × 80 mm, with 22 components from 12 distinct parts.

Its main chip is the STM32F072C8Tx, from the STM32 family. Other key parts include the LDO. By type, the board carries 7 capacitors, 6 switches, 4 connectors, 3 resistors and 2 ICs.

From the project

A big dpad for your foot

This repository contains the old V2 design of DPedal. You are probably after the V3 design at DPedal.

A large foot controlled DPad. It connects to your PC over usb 2.0 on a usb C port and sends user configurable HID keyboard events.

It consists entirely of 3d printed parts except for the PCB and keyboard switches. You can build your own from this design if you are comfortable with 3d printing, ordering assembled PCB's from a manufacturer and a tiny bit of soldering.

DPedal legacy: common questions

What microcontroller does the DPedal legacy use?

The DPedal legacy is built around the STM32F072C8Tx, from the STM32 family.

How big is the DPedal legacy PCB?

The DPedal legacy measures 154 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DPedal legacy?

22 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the DPedal legacy design files?

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

Can I use the DPedal legacy design in my own project?

Yes, under the terms of its MIT license, which rukai chose for the repository.

Can I test firmware for the DPedal legacy 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.
