ESP-01 Programmer for ESP8266

I have been working on a new wifi enabled version of the pumpkin project and as part of that effort I am using ESP8266 modules. The issue I was having is that programming them via breadboard was kinda bulky and when I ordered a PCB for a programmer it turned out to have an error in the design. The solution was to create my own. I wanted something that was minimal in parts and would just get the job done. The final product is a simple PCB with 4 components attached. To program you hold down the program button and tap the reset button and BAM! it is ready to be programmed. I left out a 3.3v regulator like lots of the other designs out there since I always use FTDI friends that have a 3.3v setting. it has made programming way simpler. I hope you find it as helpful as I did also ordering it via OSH Park 3 boards only cost $3.10.

For the build you will need:

Just solder the parts on the PCB and you are good to go.

 Here is what I was using to program a mess of wires and a pain to hook up a new esp-01 on.

Here is the bare PCB and the PCB with buttons and FTDI header installed.


  1. Looks nice, I just have ordered the PCB's, thanks for sharing!!

  2. Be that as it may, you can discover phenomenal engineers who will finish extends in an auspicious manner, with the ideal details. One key to finding amazing designers is realizing how to assess them..Techpally programming
