About the Stm32f070-board

Stm32f070-board is an open source STM32 PCB design by suyashsingh, published on GitHub. It is a 2-layer board measuring 69.6 × 31.5 mm, with 40 components from 27 distinct parts.

Its main chip is the STM32F070F6P6, from the STM32 family. Other key parts include the CH340G, MCP9700AT-ETT and SI7055-A20. By type, the board carries 12 capacitors, 12 resistors, 4 ICs, 4 diodes, 3 connectors and 3 switches.

From the project

Board design for STM32F070F6 micro-controller.

Many thanks to Balram for helping me out with the PCB design :slightlysmilingface:

2. Links that might be useful for usb connector: + Element 14 Page + Digi Key Kicad Library - Search for MPN + Mouser

3. Always do a board check when you receive the board from the fab house. You can do:

b. Check for short between the power rails - This board has 3V3 and 5V power rails. Thanks to Balram for pointing out this.

Stm32f070-board: common questions

What microcontroller does the Stm32f070-board use?

The Stm32f070-board is built around the STM32F070F6P6, from the STM32 family.

How big is the Stm32f070-board?

The Stm32f070-board measures 69.6 × 31.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32f070-board?

40 components, from 27 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 Stm32f070-board design files?

From the suyashsingh/stm32f070-board repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Stm32f070-board design in my own project?

The repository has no license, so all rights stay with suyashsingh. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Stm32f070-board 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.
