Mikroelektronika MIKROE-603 Relay 4 Board 4 Relays ULN2803 Driver

Technical description of the product (MIKROE-603):

The Relay 4 Board is a cost-effective solution for adding relays to your device. A single ULN2803 driver IC with 8 Darlington arrays drives each of the four available relays. Screw terminals allow clean and easy output relay connectivity, and a standard IDC10 connector is used for connection with development boards. Using this board with your MCU, you can switch 220V lightbulbs, DC motors, or any other device that draws up to 16A of current and up to 250V. This board enables your device to extend beyond digital output signals into the realm of higher voltages and currents.
