Ebyte E34-2G4D27SX TTL level output 27dBm UART interface 5.0km 2.4GH full-duplex wireless Serial Port data transmission module

E34-2G4D27SX Full-duplex wireless data transmission modulehigh-speed transparent transmission, low latency [Communication interface]： UART [Transmitting power]： 27dBm [Communication distance]： 5.0km [Product size]： 21*36mm [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. Electrical parameters unit model Remark Working voltage V 3.3～5.5 ≥5V can guarantee the output power. If it exceeds 5.5V, there is a risk of burning the module. Communication level V 3.3V Using 5V TTL risks burning out Power consumption Emission current mA 400 Instantaneous power consumption@30dBm receive current mA twenty one - Sleep current uA 510 Software shutdown temperature working temperature ℃ -40～+85 Industrial grade design storage temperature ℃ -40～+85 Industrial grade design Hardware parameters model Remark Modulation method GFSK New generation LoRa modulation technology Interface mode 1.27mm stamp hole - Communication interface UART serial port TTL level Packaging method SMD type - Antenna interface IPEX/stamp hole Equivalent impedance is about 50Ω size 16*26mm ±0.2mm RF parameters unit model Remark Maximum transmit power dBm 27.0±1 - Receive sensitivity dBm -101～-103 Over-the-air speed is 250kbps reference distance m 5000 In a clear and open environment, the antenna gain is 5dBi, the antenna height is 2.5 meters, and the baud rate is 9600bps.
