170MHz LoRa RF Module E22-170T30/33S Wireless Transmitter Receiver UART DIP 30-33dBm Long Range SMA-K Antenna (170M SMD 33dbm)

Description

• Adopting the new generation of LoRa spread spectrum modulation technology, it brings a longer communication distance and stronger anti-interference ability; Support serial port firmware upgrade , which makes firmware update more convenient; Support AT commands, which makes it more convenient to use; Supports automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks can run simultaneously in the same area
• Supports users to set communication keys by themselves, which cannot be read, greatly improving the confidentiality of user data; Support LBT function, which monitors the channel environment noise before sending, and can greatly improve the communication success rate of the module in harsh environments; Support RSSI signal strength indication function, which is used to evaluate signal quality, improve communication network, and measure distance;
• Support wireless parameter configuration, remotely configure or read wireless module parameters by sending command data packets wirelessly;Supports wake-up on the air, an ultra-low power consumption feature suitable for battery-powered applications; Supports fixed-point transmission, broadcast transmission, and channel monitoring;Supports deep sleep, in which the power consumption of the whole device is about 2 uA;
• Under ideal conditions, the communication distance can reach 16 km;The parameters are saved when power is off, and the module will work according to the set parameters after power is turned on again; Internal watchdog, automatically reset and resume work in unexpected situations;Supports wireless transmission rate of 2.4K~15.6Kbps ( air rate ) ;
• Application Scenario -Agricultural intelligent irrigation and environmental testing; Photovoltaic power station monitoring and distributed photovoltaic system management, etc.; Home security alarm and remote keyless entry; Wireless alarm security system; Building automation solutions;Wireless industrial remote control; Healthcare products;Advanced Metering Infrastructure (AMI )
• Supports 2.7 ~ 5.5V power supply, and the best performance can be guaranteed when the power supply is greater than 5 V; Industrial-grade standard design, supports long-term use at -40+85; The module's maximum transmission power can reach 2 W ( 33 dBm), allowing for longer and more stable transmission

E22-170Txxx is a new generation of LoRa wireless data transmission module. This series (UART) module. Its maximum transmission power is 33 dBm, with multiple transmission modes, working frequency band of 150.125MHz~173.125MHz (factory default 170.125MHz band) , TTL level output, compatible with 3.3V IO port voltage. E22-170Txxx series uses the new generation of LoRa spread spectrum technology, which is faster, has lower power consumption and is smaller in size. It supports functions such as air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key, etc. It supports packet length setting and can provide customized development services. The six modules in the figure below have the same power, different frequency bands and different packages.
