To enable this, reassign two PWM output pins as a serial UART\u2014one for TX and one for RX\u2014via the receiver&#8217;s Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while preserving the remaining PWM channels for servos or ESCs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For receivers that only provide standard servo pins, an optional adapter cable is available that converts the sensor\u2019s UART connector to two standard servo plugs (TX and RX).
