FrSky R9MX R9 MX OTG Receiver - 868MHz / 915MHz Enhanced R9MM/R9mini ACCESS OTA Long Range Receiver

Overview
The R9 MX is the enhanced versions of the previous R9 MM/Mini series long-range capable receivers, equivalent in size and weight equipped with a robust detachable Ipex1 antenna connector.
The R9 MX takes features from the previous R9 Mini and R9 MM making it compatible with more external devices by providing an Inverted S.Port output and supporting the redundancy function. Additionally, it retains soldering points to connect 4 PWM channels. The enhanced design proves to be more durable, and in conjunction with the latest ACCESS firmware, the two are now synchronized and we are able to unlock the true potential of the ACCESS protocol.
