 ## RC Input
 
-RC input is configured on the on UART4 with sh1.0 connector. It supports all serial RC protocols. DJI sbus needs solder connection for the solder pad and are connected to UART4, inversion for UART4 needs to be configured.
+RC input is configured on UART4 with an sh1.0 connector. It supports all RC protocols except PPM. The SBUS pin on the HD VTX connector is tied directly the UART4 RX. If ELRS is used on UART4, then the SBUS lead from a DJI VTX must not be connected to the SBUS to prevent ELRS lock up on boot.
 
 ## OSD Support
 
-SkySakura H743 only supports HD OSD through uart connection. However, external spi is provided and an external AT7456E can be connected to enable analog OSD.
+SkySakura H743  supports HD OSD through UART6 by default.
