{"title":"LoRa MESH Radio Module - 868MHz","handle":"lora-mesh-radio-module-868mhz","url":"/products/lora-mesh-radio-module-868mhz","description":"    LoRa MESH Radio Module is a high performance, low power, long-range micro-power RF module, using a distributed ad-hoc network communication mode, embedded wireless MESH MANET protocols, users do not need to do anything modified to present devices, protocols, nor need for secondary development to module, but can easily implement wireless ad-hoc networks. RF chip module technology based on spread spectrum frequency hopping, spread spectrum calculations and leading internal automatic CRC error correction processing. The stability, anti-interference ability and receive sensitivity are better than other types of modules. Module also supports API mode, transparent mode and AT command mode, the user can configure our PC software, or send AT commands through the microcontroller, based on the parameters of the actual demand for flexible configuration of the module, simple operation, easy to use, strong adaptation.  Recommend USB to TTL Converter to set the module parameter, and Gravity IO Expansion Shield can directly work with the Lora modules.       FEATURES         \tFrequency Range: 868/915 MHz (Sx1276) \tBased LoRa modulation techniques. \tHalf-duplex communications, serial data transparent transmission. \tEmbedded MESH distributed MANET protocols. \tEach communication has multiple handshake confirmation, to ensure the stability of the data. \tProduction free debugging, 3.4-5.5V voltage range can be customized 2.1-3.6V. \tMicro-power transmission, standard 100mW, 7-Level adjustable. \tReceive sensitivity up to -148dBm, the maximum transmit power + 20dBm. \tHigh-efficiency forward error correction coding techniques and frequency hopping mechanism, anti-interference ability, low error rate. \tSupport Serial wake, ready to send and receive data, no periodic wake-up time. \tSupport Air wake AUX signal given by the module, Wake user device. \tCAD detection LoRa signal, to prevent accidental wake. \tCommunication protocol conversion and RF transceiver to switch automatically, without user intervention, simple to use. \tCan be flexibly set the module parameters via software or microcontroller commands. \t2.54 standard pin interface, easy embedded installation, TTL level signals. \tBuilt-in watchdog to ensure long-term reliable and stable operation. \tOpen ground between nodes effective communication distance up to 2-3 km.           SPECIFICATION         \tOperating Voltage: 3.3 - 5.0V \tOperating Frequency Band: 433MHz \tOutput Power: ≤ 20dBm \tReceiving Sensitivity: -148dBm \tEmission Current: ≤100mA \tStandby Current: ≤ 20mA \tCommunication Interface: TTL serial communication \tSerial Speed: 1200 ~ 115200, 9600bps (default) \tOperating Temperature: -40 ° C - + 85 ° C \tDimension: 34.2 * 18.4 mm           DOCUMENTS     Datasheet  ","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8565,"title":"Default Title","sku":"DF-TEL0117","price":77.79,"on_sale":false,"in_stock":true,"available_quantity":21,"option1":"Default Title"}]}
