SRWF-2E86A LoRa Long distance wireless transmission module

Wireless transmission module SRWF-2E86A (2E86A) useST high speed and low power MCU and high performance SX1278 RF chip with LoRa spread spectrum technology, and at the same time, adopt effective FEC channel encoding technology, improves the anti-interference ability of wireless transmission, reduced the transmission error rate, to ensure the reliability and stability of data transmission. 2E86A provides flexible parameter configuration ability, and users can real-time configure the transmit power, channel, serial port speed, sleep mode and other parameters, which is convenient for users.

Product Information

 Product Brief : 


Wireless transmission module SRWF-2E86A (2E86A) useST  high speed and low power MCU and high performance SX1278 RF chip with  LoRa  spread spectrum technology, and  at the same time, adopt effective FEC channel encoding technology, improves the anti-interference ability of wireless transmission, reduced the transmission error rate, to ensure the reliability and stability of data transmission. 2E86A provides flexible parameter configuration ability, and users can real-time configure the transmit power, channel, serial port speed, sleep mode and other parameters, which is convenient for users.


2E86A maximum wireless transmit power is 100mW. Module is with power management chip, operating voltage range is from 3.6V to 5.5V. The static receive current of the module is 17mA, while providing two sleep modes: deep sleep mode and low power carrier wake-up mode. It is suitable for low power consumption products with battery power supply.

Application:
Active RFID tag.
IOT industrial equipment and meters.
Wireless intelligent control of municipal street lamp and lighting.
