UART MUX 2 Click Board

The UART MUX 2 Click Board™ is a compact add-on board that enables pseudo-multidrop RS232 transmission. This board features the MAX399, a precise CMOS analogue multiplexer that allows four remote RS-232 transceivers to share a single UART from Maxim Integrated. It offers fast switching speeds with a transition time of less than 250ns and low on-resistance of less than 100? while retaining CMOS-logic input compatibility and fast switching. Channel selection is performed through a set of specific GPIO pins and possesses additional functionality such as the manual ON/OFF feature. This Click Board™ is suitable for various applications, from industrial and instrumentation to consumer, communications, data-acquisition systems, and many more. The UART MUX 2 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
