I like to receive SmartPort telemetry data to my Taranis so it gives me voice feedback when something is wrong. Flight Controllers have limited hardware UARTs so I though it should be convenient to move SmartPort telemetry out of the Flight Controller and connect it thru MinimOSD as it already receives lots of telemetry via MSP protocol.
You can save an UART port when using SmartPort telemetry data if you are also using a MSP protocol compatible OSD board with Cleanflight. The method I used is to connect an Arduino Nano clone board (Atmega328) in parallel to the OSD board so we can read the MSP protocol values and send them to the receiver's SmartPort.
