This is a simple module to connect a ESP-01 breakout to 3.3V/RX/TX/GND

ESP-01 ESP8266 module needs a minimal number of resistors and it is better to have a capacity nearby.


This module puts everything needed on a little PCB.


Its also uses a resistor divider for a 5V RX compatible input.


Also gives access to GPIO 0 and GPIO 2.
