From the project

Openhardware educational platform based on the ideas of the ulx3s and Gecko4Education

This design can be used with the GECKO5Education or standalone and provides an educational base for programming related classes. In case this board is used with the GECKO5Education, the FTDI-chip is automatically routed to the integrated USB-hub, meaning that you only require one USB-C connection. In case of this situation, the USB-C connector of the GECKO5Education is disabled, and all functionality is provided by the USB-C connector of the CPU-addon board.

CpuAddOn: common questions

What microcontroller does the CpuAddOn use?

The CpuAddOn is built around the STM32F103CBU6, from the STM32 family.

How big is the CpuAddOn PCB?

The CpuAddOn measures 60.6 × 100 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the CpuAddOn?

138 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the CpuAddOn design files?

From the logisim-evolution/GECKO5Education repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CpuAddOn design in my own project?

Yes, under the terms of its MIT license, which logisim-evolution chose for the repository.

Can I test firmware for the CpuAddOn 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.
