1CH 5v Optocoupler Relay Board electronics ATtiny Microcontroller Projects: Build standalone

ATtiny Microcontroller Projects: Build standalone ATtiny85/ATtiny13 circuits for small automation tasks - the 170-point board is perfectly sized for these 8-pin DIP microcontrollers

Automated Pick-and-Place Systems: Provides reliable positioning for component placement in PCB assembly lines

FPV pilots

Test small samples with your specific printer to verify print quality before creating final products intended for sensitive applications

Ideal for automated plant watering systems

1CH 5v Optocoupler Relay Board electronics ATtiny Microcontroller Projects: Build standalone1CH 5V Optocoupler Relay Board Control high voltage appliances safely from your microcontroller with this 1 Channel 5V Optocoupler Relay Board. The built in optocoupler provides complete electrical isolation between your low voltage control circuit (Arduino, Raspberry Pi, ESP32) and the high voltage load side, protecting your sensitive electronics from voltage spikes and back EMF. Ideal for home automation, IoT switching, and industrial control
