This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 8 A at 4.5 V to 40 V. Pololu 2814
The module is equipped with eight 10A / 250VAC relays controlled independently via a serial bus (UART) or from a PC (through a microUSB connector). The NO / NC contacts of the relays have been led to the ARK screw terminals. The board recommended for use with Arduino enables the control of eight relays using only two microcontroller lines.
