4-channel SSR 240V / 2A relay module with fuse

AO3406 MOSFET transistor module with N channel and JST PH2.0 connector designed to control motor, solenoid or LEDs. Adafruit 5648

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.
