Aptinex IOT 4 channel relay module is the first IOT related device manufactured by Aptinex along with many other oncoming IOT devices. The main objective of Team Aptinex in designing this was to ease the controlling applications related to smart home ,lighting etc. This unit is based on famous wifi module ESP8266 and is having a pre-flashed firmware plus a user interface for controlling relays and changing settings.

If needed, instead of using already flashed firmware,custom made firmware can also be programmed.
