Hi makers!
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 voltages.
I recently designed a PCB according to my needs, aesthetically more beautiful and more practical. 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.
You can also use the PCB on the breadboard if you mount pin headers. I personally use it together with an ambient temperature and humidity sensor, and I access it remotely via WiFi and the Blynk App.
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.
I'm also attaching information on how you could program the ESP01/S.
