Pi serial adaptor


If you spend a lot of time building things with a raspberry pi you will eventually run into the problem that you have booted your pi it’s not plugged into a tv/monitor and it’s not connected to wifi. You don’t want to just turn it off because it could corrupt the sd card so what do you do. I recently ran into this problem but luckily I had a serial adaptor on hand to hook up and tell my pi to turn off.


I had a few serial adaptors, One being everyone’s favourite FTDI board but I also had a CP2102 on hand. It only takes a 4 jumper leads to hook up the serial adaptor to the pi which is easy enough but I wanted to make it even easier. There is a problem with using jumpers, They take up one of the 5v power pins on the pi. With my board I made I broke out all the pin so you’re not limited to one 5v power pin.

  •  CP2102
  • 5 pin female header
  • 5 pin male header
  • 6 pin male header (for CP2102)
  • PCB

The CP2102 board I was using for this was the one with a female micro usb port, You can find them with a male usb port if that’s what you prefer.

New pi’s are trouble

If you are using a raspberry pi 3 or raspberry pi zero w they used the UART pins for bluetooth so this wont work on one of these boards unfortunately, You can read up on how to get it working HERE
