1.Overview
1.1 Introduction
E34-2G4D20D is based on n, working at 2.4
～
2.518GHz,
TTL output.It’s compatible with 3.3V and 5V IO port voltage, using serial
port for data transmission and reception, reducing the threshold of wireless
applications.
The E34-2G4D20D is characterized by high-speed transmission. It can
achieve full-duplex (two-way simultaneous transmission and reception)
under various baud rates. It is not limited to packet length, supports uninterrupted transmission, and supports file
transmission.
The module has data encryption and compression capabilities. The data transmitted by the module in the air is
random, and the data interception loses its meaning through strict encryption and decryption algorithms. The data
compression function has the probability of reducing the transmission time, reducing the probability of interference,
improving reliability and transmission efficiency.
