Brief Introduction
With multiple frequency band and wide frequency range , E22 series are small size (pin spacing :1.27mm) SMD wireless transceiver
module designed by Chengdu Ebyte. It features long range transmission and super low power consumption.
The E22 series is the first wireless module in China to adopt Semtech's SX1262, SX1268 RF chip. This chip provides a variety of
modulation methods, such as LoRaTM and traditional GFSK. Its special LoRaTM modulation method increases the communication
distance. At the same time, SX126x owns two distribution methods, low-dropout regulator (LDO) and high-efficiency step-down
DC-DC converter, under the premise of the choice of DC-DC mode, the receiving current is extremely low to achieve Low power
consumption. Compared with SX127x series, SX126x can achieve up to 62.5kbps air data rate in Lora mode. In GFSK mode, air data
rate can support up to 300kbps; according to the application of choice of power management, in the DC/DC mode, when in the
maximum power output of 22dBm The SX126x's power consumption is only 118mA, and the efficiency is improved significantly. The
SX126x RF receiver power consumption is 4.8mA, which is less than half of the SX127x series' 10mA receiving current.
E22 series strictly stick to the design rules home and abroad of FCC, CE, CCC and meet the related RF certifications and export
standards. As hardware platform, users need to carry out secondary development.
