Description
Lora Sx1276 Sx1278 433 / 868MHz STM8L 3-5Km TTL LoRa Spread Spectrum MESH Wireless Transceiver ad hoc Network Module
Product Description
YL-800N is a distributed MESH network wireless ad hoc network module, working in the 433M free frequency band (customized for other frequency bands), internal automatic spread spectrum calculation and leading CRC error correction processing. The standard transmission power is up to 100mW (20dBm), and the transmission current is instantaneous. 100mA, the receiving current is 18mA, and the operating voltage range is 3.3v~5v; the module's radio frequency chip is based on spread spectrum frequency hopping technology, which surpasses the existing GFSK module in stability, anti-interference ability and receiving sensitivity. , UART baud rate 1200～115200; Built-in wireless MESH ad hoc network protocol, users do not need to make any modification to the existing equipment, protocol, and do not need to carry out secondary development of the module to easily realize the wireless ad hoc network. MESH is a distributed peer-to-peer mesh network. It can make full use of the routing redundancy in the network. It has excellent network self-healing, stability and excellent data throughput. Its networking speed is zero. The device works immediately after power-on, and supports 255-level routing and a large networking scale of tens of thousands of nodes. The physical layer uses many advanced wireless communication technologies such as frequency hopping, adaptive rate, safe and reliable wireless wake-up technology for the entire network, and interleaving error correction coding; the link layer uses intelligent collision avoidance algorithms, which have excellent anti-interference capabilities.
Feature
Medium power transmission, maximum 100mW, adjustable. Lora spread spectrum modulation method, half-duplex communication, air receiving/transmitting conversion, embedded MESH distributed self-organizing network protocol, each communication has multiple handshake confirmations to ensure data stability. Working frequency band: 315/433/490/868/915MHz and other application-free frequency bands Receiving sensitivity -148dBm, the open transmission distance is more than 1500 meters, the line height is 2 meters, the open area can reach 2Km without interference Transmitting working current is less than 100mA, and transmitting power is up to 20dB Standby working current is 18mA, TTL interface. The standby current of low-power products can reach 0.1mA, which is especially suitable for several recordings of water meters and gas meters and centralized collection of sensor data. Arbitrary setting of communication frequency, 32 auxiliary channels, automatic frequency hopping, effectively avoiding interference. Communication protocol conversion and RF transceiver switching are automatically completed, and the user does not need to interfere, and it is easy to use Communication rate 1.2kbps -115.2kbps, users can configure through software Production debugging free, wide voltage range work: 3.3V-5V, industrial grade application
