About PHPoC Smart Expansion Boards
PHPoC Smart Expansion Boards provide the additional hardware and firmware to boost PHPoC IoT board with the advanced capabilities (e.g. control high-voltage devices, control/monitor motors with high accuracy). Smart Expansion Boards communicate with PHPoC Black/Blue as master and slave way via a definite set of commands, through a specific port.
A smart expansion board is stackable on PHPoC IoT Board and specified by a slave ID number among 14 different ID numbers available, which can be set by a DIP switch.
A single PHPoC Blue or Black can carry multiple smart expansion boards, in which the types of these boards can be the same of different.
About 4-Port Relay Board / PES-2401
4-port Relay Board is a PHPoC smart expansion board, which is designed to control on/off high-voltage devices. By stacking on PHPoC Blue or Black, this board can be controlled by PHPoC Blue/Black via a definite set of commands, through a specific port.
Each 4-port Relay Board carries four relays. A single PHPoC Blue or Black can carry multiple 4-port Relay Boards.
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.
