About the Hw cpu PCB

Hw cpu is an open source STM32 PCB design by andreili, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 150 × 75.4 mm, with 100 components from 39 distinct parts.

Its main chip is the STM32F429ZGTx, from the STM32 family. Other key parts include the LM2596S-ADJ, MC34063, MT48LC32M16A2P, K9F5608 and SP3485CN. By type, the board carries 45 capacitors, 28 resistors, 7 diodes, 6 ICs, 5 switches and 4 connectors.

From the project

The project is open source and open hardware, the purpose of which is to create a PLC based on STM32 MCU's.

Hw cpu: common questions

What microcontroller does the Hw cpu use?

The Hw cpu is built around the STM32F429ZGTx, from the STM32 family.

How big is the Hw cpu PCB?

The Hw cpu measures 150 × 75.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hw cpu?

100 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hw cpu design files?

From the andreili/STM32-PLC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Hw cpu design in my own project?

Yes, under the terms of its GPL-3.0 license, which andreili chose for the repository.

Can I test firmware for the Hw cpu 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.
