00:00The E220T Series LoRa module is a low-power, long-range, wireless serial communication
00:06module designed based on Semtex LLCC68RF chip.
00:10It enables stable and reliable long-distance wireless data transmission.
00:13This series offers multiple module options to suit different frequency bands and power requirements.
00:18There is also a plus version module with a 32 meters high-precision temperature compensated crystal oscillator
00:23as well as a test evaluation kit available.
00:25The E220T Series modules have seven core features.
00:28It's first feature is ultra-long-range interference resistance.
00:31It uses LoRa spread spectrum technology, allowing communication range of up to 10 kilometers, remaining stable even in complex
00:36environments.
00:37The second feature is low-power consumption, supporting wake-up over the air.
00:40The current is only 3A in sleep mode, allowing the device to operate for a long time on battery
00:45power.
00:46The third feature is flexible transmission modes.
00:48It supports multiple modes such as point-to-point broadcast and carrier sensing.
00:52The fourth feature is safety and reliability.
00:54Communication keys can be set, and a watchdog mechanism is built in.
00:58Abnormal situations can be automatically recovered from.
01:00The fifth feature is dual command configuration.
01:02It supports both hex and a dual command systems, allowing users to choose flexibly.
01:07The sixth feature is firmware upgrade, supporting serial port firmware updates, making maintenance more convenient.
01:12The seventh feature is industrial grade quality, with an operating temperature range of 40 to 85, suitable for harsh environments.
01:20This series of modules has been widely used in IAT fields such as smart metering, smart agriculture, smart
01:25cities, industry, and security.
01:28Long distance transmission, low sleep power consumption, and multi-node features provide an efficient wireless connection solution
01:33for various IAT applications.
