Smart Expansion boards for PHPoC Shield provide the additional hardware and firmware to boost Arduino Uno/Mega with the advanced capabilities (e.g. control high-voltage devices, control/monitor motors with high accuracy). Smart Expansion board for PHPoC Shield communicates with Arduino Uno/Mega via a definite set of commands. They are interfaced with Arduino through a PHPoC [WiFi] Shield. A Smart Expansion board for PHPoC Shield is stackable on Arduino Uno/Mega and specified by a slave ID number among 14 different ID numbers available, which can be set by a DIP switch. A single Arduino Uno/Mega can carry multiple smart expansion boards, in which the types of these boards can be the same or different.

4-port Relay Board is a Smart Expansion board for PHPoC Shield, which is designed to control on/off high-voltage devices. After stacking on PHPoC Shield and Arduino Uno/Mega, this board can be controlled by Arduino via using PHPoC library. Each 4-port Relay Board carries four relays. A single Arduino Uno/Mega can carry multiple 4-port Relay Board. Two different types of terminal blocks are available, based on the direction of the terminal screws. S-type can be screwed from the side, convenient when the multiple boards are stacked. T-type is screwed from the top of the board. The wire termination blocks are on the side of the board in both models. |
