E34-2G4D27SX Full-duplex wireless data transmission modulehigh-speed transparent transmission, low latency
[Introduction]：E34-2G4D27SX product is a full-duplex wireless data transmission module developed by Ebyte. It works 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. Under a variety of baud rates, it can achieve full-duplex characteristics (simultaneous bidirectional transmission and reception), unlimited packet length, support uninterrupted transmission, and support file transfer.
