OrbiCraft Pro SXC-UHF-02 transceiver is a PC/104 stackable PCB with SMA antenna con-nector and auxiliary antenna deployment interface. 
 
The transceiver uses reprogrammable central frequency in 434-436 MHz range and a band-width not wider than 20 KHz achieving baud rate up to 9600 when in GMSK modulation mode. This speed is quite enough to exchange telemetry, commands, and data from modest payload. Maximum output power of 1 W is optimized for LEO transmissions as well as typical receiver’s sensitivity of -119 dBm. UHF transceiver operates in -40..+85 degrees temperature range and weighs about 40 g. It is compatible with OrbiCraft Pro PC/104 pinout and has an additional fea-ture of UART interface. Transceiver also runs watchdogs and a real-time clock which value is available on redundant CANx2 bus, this RTC has backup super capacitor power and keeps up ticking for about 2 weeks after main power is down.

Features:
•    Half-duplex communication via single antenna
•    Single board radio for telemetry, telecommand and beacon
•    In-flight reconfigurable beacon period, datarate, frequency, call sign etc.
•    In-flight firmware update via RF with backup
•    Hardware and software watchdogs
•    Customizable beacon message
•    Ground to board bridge mode
•    RTC with backup power
•    Rich telemetry

Configuration:
•    Operation frequency, baudrate, call sign
•    Beacon contents and period
•    RF connector type and orientation (on demand)
•    Watchdog period
•    CAN bus data rate
