Ebyte E34-2G4D20SX TTL level output 20dBm UART interface 2.4GH full-duplex wireless Serial Port data transmission module

E34-2G4D20SX Full-duplex wireless data transmission module Automatic frequency hopping anti-interference low latency high-speed serial [Communication interface]：UART [Transmitting power]：20dBm [Communication distance]：2.0km [Product size]：16*26mm [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. 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 110 Instantaneous power consumption@30dBm receive current mA 21.5 - Sleep current uA 75 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 Electrical parameters unit model Remark Maximum transmit power dBm 20.0±1 - Receive sensitivity dBm -101～-103 Over-the-air speed is 250kbps reference distance m 2000 In a clear and open environment, the antenna gain is 5dBi, the antenna height is 2.5 meters, and the baud rate is 9600bps.
