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 :DOS multi-rotor firmware version V2.2 and above is not support connect the Hornet-OSD. Please
do not connect the Hornet-OSD to DOS GPS port.
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 Hornet-OSD, 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.
Attention : DOS multi-rotor firmware version V2.2 and above you can only connect the Hornet-OSD to DOS
UART port. Please do not connect the Hornet-OSD to DOS GPS port. And please upgrade Hornet-OSD
firmware to V1.7.
 ESC output interface
DOS’s S1 ~ S8 ports are connected separately to ESC M1 ~ M8.
Typically 1020us is lower limit, 1520us is neutral and 2020us is upper limit, frequency is 400Hz.
