To plug the ESP-201 in the breadboard is necessary to remove the 4 pin connector from the botton of the board and install it in the component side.

A quick pinout reference to start the wiring:

ESP-201_pinout

Note: GPIO9 and GPIO10 are connected to the FLASH memory (may be unusable). Here is a “surgery” procedure to use them: ESP-201 board modification

First experiment sending the analog value from A0 to ThingSpeak:

ESP-201_A0

 

Experimenting with different antennas:

Best results with the external antenna (the metal one):
