The module consists of two relays controlled by a USB socket. The controlling computer can work on the basis of Linux or Windows.
The module is widely used in projects that require high current loads as external control. This device can be used as an actuator in smart home and other systems. The work of the relays is handled by the Attiny microcontroller, which receives signals from the USB port and executes them.
Inputs for controller programming are derived from the Attiny system.
A program for handling relays is available HERE.
