* SBUS pad has a built-in inverter and is connected to UART2 RX

## Available TARGETS

* `MATEKF411SE` Stock target. LED control and have SS1 on ST1 pad, SS2 on TX2 pad.
* `MATEKF411SE_PINIO` Adds USER 2 PINIO support on the LED pad.
* `MATEKF411SE_FD_SFTSRL1` Adds full duplex SS1 by putting the RX on the LED pad.
* `MATEKF411SE_SS2_CH6` SS2 moved to Ch6 pad. This keeps UART 2 as a full UART (for example, for use with Crossfire) and SS2 support.
