Product Introduction:
ARKBIRD-433UHF is a 10-channel module designed for long-distance flight:
1. The advanced code division frequency hopping system (FHSS) produces the only way of frequency
hopping sequence according to the only ID code of each transmitter, and receives it by different ID
addresses with fast frequency hopping at full frequency;
2. Adjustable power (100mw-1400mw);
3. Both Tuner mode and Repeater station mode are optional, plug and play and automatically identify.
Repeater mode can be compatible with all radio TXs;
4. No welding setup, wires are connected easily;
5. Receiver 10-channel Servo output interface, PPM output, 3.3V RSSI output interface, and head sensor
interface;
6. Rapid response of 20ms, without delay.
With Arkbird OSD, it has the following functions:
7. It can be configured to single-wire PPM&RSSI output, three-wire transmission of 10-channel signal
and RSSI, with very simple wire connecting; (Arkbird OSD needs to be upgraded to 3.1020 or newer
firmware)
8. The original channel 1-4 input ports on Arkbird OSD; automatically become output ports which will
output channel 7-10 of the radio TX control;
9. Output channel 9 and 10 can be configured to steering A Servo-Stabilizing-Gimbal for camera. Positive
or negative, and the amount of stability augmentation can be adjusted.
Transmitter: working voltage: 2S-3S（7～12.6V） peak current: 400mA@12V
Receiver: working voltage: 4～12V peak current: 120mA@5V
Attention:
Read the instructions carefully before using, pay attention to details and wire connection, and avoid
the missing of important messages, which may become a hidden danger for the flight.
