PES-2607, smart RS-422/485 board, is one of smart expansion boards for PHPoC Shields for Arduino. You can easily implement the RS-422 or RS-485 communication on the Arduino board by using this board and a PHPoC shield.
※ Caution : Both a PHPoC shield with R2 or later version and an Arduino board are required to use this board!
What is the Smart Expansion Board for PHPoC shield?
A smart expansion board for PHPoC shield has own devices and firmware. This board communicate with a PHPoC shield in a master-slave protocol through the designated port. Two or more smart expansion boards can be connected to one PHPoC shield and each of them required to be setting a slave id.
