[Introduction]：E34-2G4D20SX product is a full-duplex wireless data transmission module developed by Ebyte, which operates in the 2.4-2.518GHz frequency band, has TTL level output, is compatible with 3.3V and 5V IO port voltages, and uses a serial port for data transmission and reception. The typical characteristics of the wireless module are high-speed transmission, and it can achieve full-duplex characteristics (simultaneous bidirectional transmission and reception) at a variety of baud rates, with no limit on packet length, support for uninterrupted transmission, and support for file transmission.
