  • Description

    The NavWave Systems UHF Board is a CC1200-based radio board operating in the Sub-1 GHz frequency range, tuned between 420 MHz and 470 MHz. The board provides a dedicated Tx port for RF output and a separate Rx port. It also includes auxiliary transmit and receive ports.

    An onboard STM32H733VG microcontroller manages the system configuration and allows parameters such as data rate, operating frequency, channel spacing, frequency deviation, and Rx bandwidth to be set programmatically. The board accepts a 9V–36V DC input and provides RS-232, Ethernet, GPIO, and RF connectivity. All RF inputs and outputs use SMA female connectors with 50 Ω impedance.
