RS232 4 Click is a compact add-on board that provides a reliable RS232 interface solution for asynchronous serial communication, ensuring data exchange between microcontrollers and external serial devices. It is based on the TRSF3232E, a two-channel RS232 line driver and receiver from Texas Instruments, which integrates two drivers, two receivers, and a dual charge-pump circuit to generate the necessary RS232 voltage levels from a single supply. It features ±15kV ESD protection on all serial-port connection pins, supports data signaling rates up to 1Mbit/s, and maintains a controlled driver output slew rate of 14V/μs to 150V/μs for stable and distortion-free transmission. RS232 4 Click is ideally suited for industrial PCs, wired networking, enterprise and data center equipment, portable systems, and various handheld or battery-powered devices requiring secure and high-speed RS232 communication.

RS232 4 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to automatically detect and identify this add-on board.

UART MUX 2 Click is a compact add-on board that enables pseudo-multidrop RS232 transmission. This board features the MAX399, a precise CMOS analog multiplexer that allows four remote RS-232 transceivers to share a single UART from Analog Devices. It offers fast switching speeds with a transition time of less than 250ns and low on-resistance less than 100Ω while retains 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 a wide range of applications, from industrial and instrumentation to a consumer, communications, data-acquisition systems, and many more.

UART MUX 2 Click 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.
