It keeps the advantages of RFIC SX1272 but simplifies the circuit design. The high sensitivity (-137dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications.<\/p>\n<p>iL-LORA1272 module consists of RFIC SX1272 and include powerful MCU, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don\u2019t need to spend time in RF circuit design and choose suitable antennas for different applications. iL-LORA1272 operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications. Because iL-LORA1272 is purely hardware module and it adopts \u00b110ppm crystal which the resolution of it places a important role in calculating spreading factor, bandwidth, etc.<\/p>\n<p>In addition, We\u2019er add powerful MCU to help Users that don&#8217;t needs to read the datasheet of SX1272, you just go through UART to control this module and will easy to use the module in the best performance.<\/p>\n<h2>\u00a0Document<\/h2>\n<p>PPT download\u00a0<a href=\"http:\/\/www.powenko.com\/download_release\/ifroglab\/Maker Hatch Meetup- PowenYanni (20160811)_v2.pdf\">here<\/a><\/p>\n<p>UART data spec PDF\u00a0<a href=\"http:\/\/www.ifroglab.com\/download\/UARTCmd_SocLoraV5.pdf\">here<\/a><\/p>\n<p>Application Note <a href=\"http:\/\/www.ifroglab.com\/download\/iFroglab_LoRa_Apps_01.pdf\">Here<\/a><\/p>\n<h2>Source Code<\/h2>\n<p>github <a href=\"https:\/\/github.com\/iFrogLab\/IL-LORA1272\">download<\/a><\/p>\n<h3>LoRa Gateway<\/h3>\n<p>Docker Container <a href=\"https:\/\/hub.docker.com\/r\/ifroglab\/loragateway\/\">here<\/a><\/p>\n<p>Tutorial \u00a0<a href=\"http:\/\/www.ifroglab.com\/en\/?p=6613\">here<\/a><\/p>\n<h2>Demo and tutorial:<\/h2>\n<p><iframe title=\"SX1272 Based LoRa USB Dongle Gateway 868\/915MHz | Plug &amp;
