About the Hector PCB

Hector is an open source STM32 PCB design by RickKross, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 275.7 × 105.4 mm, with 178 components from 17 distinct parts.

Its main chip is the STM32F303RETx, from the STM32 family. Other key parts include the USBLC6-2SC6 and RT9013-33GB. By type, the board carries 66 capacitors, 12 resistors, 6 ICs, 4 connectors, 4 switches and 4 inductors.

It belongs with the keyboards and sensors designs in this gallery.

Hector: common questions

What microcontroller does the Hector use?

The Hector is built around the STM32F303RETx, from the STM32 family.

How big is the Hector PCB?

The Hector measures 275.7 × 105.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hector?

178 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hector design files?

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

Can I use the Hector design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which RickKross chose for the repository.

Can I test firmware for the Hector 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.
