Texas Instruments BoosterPack BOOSTXL-RS232 Getting Started Manual

Meet the BOOSTXL-RS232™ BoosterPack. This BoosterPack provides the opportunity to communicate to
and from TI LaunchPads™ using the RS232 serial protocol. The featured product is the TRS3122E, an
ultra-low power, high-speed dual RS232 transceiver. It supports data [RX, TX] channels as well as flow
control [RTS, CTS] channels that can easily be assigned to 1 of 10 GPIO pins. This device features a
shutdown mode that reduces supply current as low as 0.5 µA. This can be done manually or by setting the
