The RS232 Isolator 2 Click Board™ is a compact add-on board containing a fully isolated transceiver that provides secure and easy UART to RS-232 conversion. This board features the ICL3221, a 3.3V powered RS-232 transmitter/receiver that provides ±15kV ESD protection on its RS232 pins from Renesas. This Click Board™ is characterised by an assured minimum data rate of 250kbps. It features an automatic power-down function and uses high-speed digital optocouplers to isolate the RS-232 interface for 3.75kV isolation. It also possesses an LED indicator indicating a valid RS-232 signal at any receiver input. This Click Board™ is suitable for isolation of RS-232 signals portable equipment, where the low operational power consumption and even lower standby power consumption are critical.
The RS232 Isolator 2 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
