		COFDM Two-way FDD Transceiver Module	21 Jan, 2024 released
		A bidirectional transmission wireless link module, composed of two independent unidirectional wireless channels, and the wireless links in both directions operate in different frequency band. The wireless link itself does not have a handshake protocol, so when one direction of the wireless link is interrupted by interference, it does not affect the data transmission of the other direction of the wireless link. The Ethernet port supports TCP/UDP/IP protocols. -- COFDM two-way FDD(Frequency Division Duplexing) wireless Transceiver. -- Support bidirectional transparent data transmission via Ethernet/uart ports. -- AES256 encryption /decryption. -- Control uart for management.
