My handy breakout board for the bluepill
My new favourite board for small projects is the bluepill. I find bread boards and dupont hook up cables to be unreliable and I would prefer most of my project to be more permanent, so i’ve designed a handy breakout board to ease the creation of new designs. You can see the final board above.
This board has the following features:
- Breakout for every pin which is clearly labelled and can be easily cut if required.
- Top copper pour is connected to 3V3 and can be accessed close to each IO pin.
- Bottom copper pour is connected to ground and can be accessed close to each IO pin.
- USART1 has a separate connection at the bottom left to be connected to a FTDI cable
- Prototyping areas in each corner of the board.
Here is a photo of the board in use with the stlink programmer and a UART to USB cable connected.
The board is 2-layer, here is a render of the top layer:
And here is a render of the bottom layer:
I had cheap boards made at JLCPCB using the files below and they work very well for my needs:
