Hello PCBWayers!

You probably know that ESP01S/01 boards can be a little difficult to use in an easier way, and they don't fit classic breadboards. Over time, I've made a few adapter circuits, first for the breadboard; then a programming circuit using the FTD232RL, and step 3 was to build a circuit that would allow me to use the module at 5V.

I recently designed a PCB according to my needs, aesthetically more beautiful and more practical then the older version. It's a small, simple and effective PCB, but which can help us a lot. We have the ESP module, 3.3V regulator, pin headers (male/female, mount them as you want) and 1 LED indicator.

For the ESP01 to run the program, it is necessary for the CH_PD pin to be pulled-up to 3.3V or 5V, through a simple wire.

You can also use the PCB on the breadboard if you mount pin headers.

Buy it or download it.

I'm also attaching information on how you could program the ESP01/S.

Have a nice day!
