Ai Thinker LoRa Series Ra-01H Spread Spectrum Wireless Module

Ai-Thinker lora Series Module (Ra-01H) designed and developed by Ai-Thinker. This module is used for long distance spread spectrum communication.. Its RF chip SX1276 (as show as figure 1) Mainly. used LoRa remote modem, for ultra-long-distance spread spectrum communication, strong anti-interference, can minimize current consumption. With the help of the SEMTECH the patent technology of LoRa SX1276 with -148dBm high sensitive, with +20dBm power output, long range transmission, high reliability. Meantime, relative traditional modulation technique. LoRa modulation technique has obvious advantages in anti-blocking and selection, It solves the problem that traditional design scheme can not consider distance, anti-interference and power consumption simultaneously. Its application can be automatic meter reading, home building automation, security system, remote Features:- LoRa modem. Support FSK, GFSK, MSK. GMSK. Lola and OOK mode Support 803/930MH Operating voltage is 3.3V,maximum output 19dim. the maximum output current is 105mA Low power Consumption in a received stat, the received current is 12.15mA, stand-by current is 1.6m High sensitivity as low as 140dBm Small volume double row stamp hole patch package SPI interface, using half duplex communication, with CRC. up to 256 byte packet engine Specifications:- Module : Ra-01H Package : SMD-16 Size : 17x16x3.2(+0.2)mm Antenna : Compatible half hole weld tray (need to weld antenna) Spectrum range : 803 930MHz Working temperature : -40℃ ~ 85 ℃ Storage temperature : -40 ℃ ~ 125 ℃ , < 90%RH Power supply : 2.7-3.6V, typical value 3.3V, current over 200mA Support Interface : SPI Programmable bit rate : 300kbps Package Includes:- 1 x Ai Thinker LoRa Series Ra-01H Spread Spectrum Wireless Module
