N427AS high power LORA radio module based sx1272, PA and LNA.

N427AS integrated sx1272 transceiver, high power PA and LNA chip, suitable for 868MHz, 915M and 1200MHz band.

N427AS high power module output power is +33 dBm. SX1272 transceiver module has the characteristics of low cost, low power consumption and small size. The transceiver module is designed with 4-layer board, with excellent impedance matching and anti-interference. The module is mainly for IoT, intelligent home, wireless meter reading, scientific research and medical treatment, and medium and long-distance wireless communication equipment. N427AS leads all pins of SX1272 out for secondary development. The module support LoRaWAN protocol.

N427AS Technical Characteristics

APPLICATIONS

LoRa network generally consists of terminal equipment, gateway equipment, network server and application server.

The terminal equipment is generally a small module or a terminal equipment with embedded modules. The transmission distance of such equipment can reach several kilometers, such as water and electricity meters, smoke alarms, pet trackers, logistics locators, etc.

Gateway devices are generally used to receive data sent by terminal devices and send them together. Therefore, they are usually called LoRa concentrators. When data is collected together, they are usually sent together. According to the network sending data, they can be divided into LoRa Ethernet gateway and LoRa-4G gateway.

The network server is generally a server built on the cloud, which is used to process the parameters uploaded by LoRa gateway and nodes, and belongs to the device server.

The application server is a client oriented server that converts data and provides it to users.
