ESP8266 small signal relay module utilizing an ESP-12-F wifi module for communication and MCU, and has two 2.5-25V inputs, and a single 25v, 100ma high speed open drain output through a TBD062003 DMOS transistor array ic. The three relay outputs are capable of driving around 25V 500ma.
Thanks to u/PricelessToolkit/ESPClicker for inspiration. If you need a ready to use product you should so head over to his store and buy his version.
