        # Hardware Board Design for STM32F070F6

`STM32F070F6` is a 32-bit ARM Cortex-M0 microcontroller from ST. This repository contains the hardware files needed for creating a basic board for working with this micro controller. 

EDA Tool: **KiCad(5.0.1)**.

**Many thanks to [Balram](https://www.linkedin.com/in/balram-jatav/) for helping me out with the PCB design :slightly_smiling_face:**

## Board Bring Up Checklist

- [x] 1. Change trace width of power tracks

- [x] 2. Merge `dev` branch to master

- [x] 3. Export gerbers - research about fab houses

- [x] 4. Verify gerbers

- [x] 5. Send board to fab house

- [x] 6. Generate BOM

- [x] 7. Order component and tools

## Notes

1. Changed the switches with were earlier decided from *robu.in* to [this](https://in.element14.com/alcoswitch-te-connectivity/fsmsm/switch-spst-0-05a-24vdc-smd/dp/1703878) from element14, as mechanical dimensions were not available.

2. Links that might be useful for usb connector:

	+ [Mouser](https://www.mouser.in/ProductDetail/Molex/47346-0001?qs=c2CV6XM0DweJBWaSeyWeCw%3D%3D)

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

	

	a. Visual Inspection

	

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