Maxim's MAXREFDES62 RS-485 communication micro PLC card has two RS-485 transceivers with isolated power and data.
This reference design integrates a half-duplex RS-485 transceiver (MAX14783E). 1 full-duplex RS-485 transceiver (MAX14789E); 600VRMS data isolation (MAX14850); STM32F1 microcontroller; FTDI USB-UART bridge; isolation / regulation + 3.3V power rail (MAX17498C / MAX17515).
The entire system typically runs at less than 500mW and fits into a credit card-sized space. Although suitable for industrial and micro PLC applications, it can be used for any application that requires high RS-485 data rates and ESD protection. ?
