Image shown with ESP-01s module (sold separately) fitted.
This relay module is designed for the ESP-01s ESP8266 module. It features a 6 pin IDC socket designed to connect the ESP module without the need for any soldering. The relay can then be directly controlled via the ESPs GPIO0 pin. The relay is capable of switching up to 250V AC or up to a 5A load. Screw terminals provide convenient connection of module power (5V) and also to the relays NC, COM, & NO contacts. Also fitted to the module is a reset switch and an LED which indicates the state of the relay.
NOTE: This module is compatible with the ESP-01s. It is not compatible with the older ESP-01 version.
