Relay module 4 channels + Bluetooth 4.0 BLE - 10A / 250V contacts - 5V coil

The module has four SRD-05 relays with a coil powered with the voltage of 5 V, it was also equipped with a module Bluetooth 4.0 BLE allowing ot control the devices via Android or iOS device with the appropriate app.

For proper operation, it is sufficient to connect the power supply of the relay's coil and the digital control signal or the respective application. The pins are the screw ARK connectors that are connected by wires with the removed insulation at the ends.

App for Android can be downloaded here.

For iOS devices, look for the TwoSwitchBle app in the AppStore .
