About the GeneralMCU PCB

GeneralMCU is an open source STM32 PCB design by ParadigmHyperloop, published on GitHub under the Custom license license. It is a 2-layer board measuring 30 × 80 mm, with 87 components from 50 distinct parts.

Its main chip is the STM32F303R6TX, from the STM32 family. Other key parts include the SN65HVD230, AZ1117-3.3, P78E05-1000 and DS18B20. By type, the board carries 30 capacitors, 19 resistors, 7 diodes, 5 ICs, 5 connectors and 3 jumpers.

In summary, (you still need to read the whole thing), these boards are for Paradigm, and Paradigm only. It is shared with the world for the benefit of observers and potential Paradigm team members. If you wish to utilize these designs in any way, you must contact us first and receive written permission to utilize the designs for the purpose you require.

We don't want to be restrictive, and we will almost certainly grant you permission, but we want to know what you are using our designs for, and we want to make sure you are using them correctly and safely.

GeneralMCU: common questions

What microcontroller does the GeneralMCU use?

The GeneralMCU is built around the STM32F303R6TX, from the STM32 family.

How big is the GeneralMCU PCB?

The GeneralMCU measures 30 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GeneralMCU?

87 components, from 50 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 GeneralMCU design files?

From the ParadigmHyperloop/comp5-electrical repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the GeneralMCU design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the GeneralMCU 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.
