Hello members, I am planning on purchasing the Typhoon H plus drone. However, I’m having trouble finding a technical manual with the following specific information about the aircraft (not just the ST16S controller):
  1. How many data channels are free (not already used by features that come with the drone)
  2. What is the format for the data channels (UART? If so, what is max baud rate)
  3. Connector location and pinouts
 
I think the only channel that is not used to control the drone and gimbal by default is the Aux button. But as far as I know there is no way to use that aux button to control anything. I'm not aware of a connector on the flight controller that you could hook anything up to have it controlled by the aux button. The receiver is attached to the flight controller via a serial connection and the protocol is understood, so I suppose it would be possible to tap into the serial connection and create a device that listens to the packets and controls something via the aux button.

The radio connection protocol between ST16 and drone is ZigBee. The channels are packed in data messages, each channel 12bit. Message description is here: H480_UART_reading/docs/SR24UART_messages.ods at main · h-elsner/H480_UART_reading

The UART between receiver SR24 and flight controller has baud rate 115200 8N1.

As @dylanfm said with given FW ST16 uses 12 channels. The drone uses 11 channels, AUX channel is not handled by FW as far as I know. All in all it is a closed system with little room for own extensions.
