MOD-34 / A.Z - remotely controlled executive module with relay

Remotely controlled executive module with relay (without module nRF24L01)

Description

The module enables remote switching on and off of systems operating with voltage or current other than that used by the control system.

For example, when we want to connect an LED strip powered with +12 V to a microcontroller, we can not do it directly, due to the microcontroller operating voltage limitation. Then an executive module acting as a switch should be used. The module must be powered via a USB connector or via a pin connector. The output connectors of the relay are connected to the power supply circuit, just like a normal mechanical switch, using 2 out of 3 available pins, middle and extreme. Depending on which of the extreme pins we choose, the module will short-circuit or open the circuit, i.e. switch the controlled system on or off.

The set does not contain the radio module nRF24L01.
