UART to RS232 converters are very useful for interfacing a microcontroller with an RS232 device such as the GSM modem, RFID reader, etc. Therefore, RS232 Isolator click is a handy device to have.
RS232 Isolator click
RS232 Isolator click is a fully isolated dual transceiver click, used to provide secure and easy UART to RS232 conversion, with the galvanic isolation.
The click can be used for galvanic isolation of RS232 signals. For example, when operating in harsh environments where electrostatic discharges (ESD) can occur, when the RS232 cable is plugged in and out frequently, and generally - wherever the sensitive part of the RS232 controller logic circuitry needs to be protected.
