About PHPoC Expansion Boards
PHPoC Expansion Boards provide the additional hardware (such as Breadboard, RS232, RS422, RS485 and so on) to enhance capabilities of PHPoC IoT Board, and standardized connectors and sockets (such as 3-pin interface, Grove interface, mikroBUS™ socket, pitch terminal block and so on) to create the firm connection to external devices.
This board is stackable on PHPoC IoT Board. Pinouts of expansion board connect directly to pins of PHPoC IoT Board.
About RS422/RS485 Board / PES-2202
RS422/RS485 Board is a PHPoC expansion board for RS422 or RS485 communications. The type of the communication port is 5mm pitch 1x6 terminal block and it is equipped with 3.9k biasing resistance. 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. This board is stackable on PHPoC IoT Board (PHPoC Black and PHPoC Blue). It can be used for not only prototype but also production as a component.
Features
- 1x6 5mm pitch terminal block interface
- 2.54mm pitch 1x6 Hole for RS422/485
- UART jumper (either UART0 or UART1)
