SW1 can be used to switch DoS flight modes by any 2 or 3-position
switch.SW2 is unnecessary in firmware V2.0.
GPS and UART interface
GPS module interface
The GPS pin interface consist of: GND, +5V , RX0. The characteristics are:
Baud rate: 38400
Data bits: 8
Stop Bits: 1
Parity: None
Interface Features: TTL level
This port is use for GPS Receiver. The GPS data protocol is standard NEMA0183.
Attention:
FY-DoS firmware V2.0 has no GPS navigation function
,so the GPS interface
is not used.
Data Radio interface
The UART pin interfaces consist of: GND, power 5V , TX1, RX1.
The characteristics as follows:
Baud Rate: 19200
Data bits: 8
Stop Bits: 1
Parity: None
Interface Features: TTL level
This pin interfaces connects to the Data Radio, PC computer serial port or OSD module.
You can set DoS control parameters and upgrade DoS firmware through this interface. For
the firmware upgrade,please refer to the firmware update operation manul.
