-If your SBUS receiver don’t need to be inverted signal(such as Full Speed’s receivers), please use the D/S/P port one the up side.
-If your SBUS receiver need to be inverted signal, please use the SBUS port on the other side.
-The FSD F411 flight controller will support a gyro loop rate of up to 32khz however maximum pid loop frequency is limited to 16khz. To run at this speed you will need to overclock the CPU by entering the code: Set cpu_overclock = 120mhz in CLI.
-In betaflight 3.4.0 and above CPU temperature can be monitored directly in betaflight osd.
