Dual relay control on one board, with signal optical isolation.
4-channel relay control board with optical isolation.
8 relays, optically isolated, perfect for Arduino projects!
Single channel relay for ESP8266 and ESP32 modules.
Single Channel Relay for Grove
This DPDT 5V relay is used for a good many robot projects, usually for motor power routing.
The Crydom D2W203F Solid State Relay is a simple way to activate AC loads. Use a DC input from 3-32VDC to control an AC output up to 240AC, to a maximum of 3 Amps.
This PCB mount mechanical relay allows isolated control of AC or DC voltage at up to 12A @ 250VAC (see datasheet for details).
Up to 40V 16A Latching Push-ON, push OFF DC switch with micro-controller friendly inputs.
The Grove latching relays are interesting because they take a pulse to toggle their state, which it maintains even after a power cycle.
Think of a Grove-compatible relay with no moving parts!
Single channel optically-isolated relay board
It's a convenient way to add 4 channels of major power-control to your Arduino with a minimum of fuss.
