These flexible and cost-effective receivers offer numerous connectivity options in a 16 x 12.2 x 2.4 mm miniature package. Its compact architecture and power and memory options make GT-U7 modules ideal for mobile<\/p>\n<p>devices that run on battery-powered batteries with very strict cost and space constraints. The u-blox 6 50-channel positioning<\/p>\n<p>engine features Time-To-First-Fix (TTFF) of less than 1 second. The dedicated acquisition engine, with 2 million correlators, is capable of performing massive time\/frequency space searches in parallel, allowing you to<\/p>\n<p>find satellites instantly. Innovative design and technology suppress interference sources and mitigate multipath effects, giving GT-U7 GPS receivers excellent navigation<\/p>\n<p>performance even in most challenging environments.<\/p>\n<p><strong>Assisted GPS (A-GPS)<\/strong><\/p>\n<p>Providing help information such as ephemeris, almanaque,<\/p>\n<p>last approximate position and hour and satellite status and an optional time sync signal will significantly reduce the time to fix for the first time and improve acquisition sensitivity. All GT-U7 modules are compatible with u-blox AssistNow Online and AssistNow Offline A-GPS11 services and are compatible with OMA SUPL.<\/p>\n<p><strong>AssistNow Autonomous<\/strong><\/p>\n<p>AssistNow Autonomous provides functionality similar to assisted GPS without the need for an external network host or connection. Based on satellite ephemeris data previously downloaded and stored by the GPS receiver, AssistNow Autonomous automatically generates accurate satellite orbital data (“AssistNow autonomous data”) that can be used for future GPS positions. AssistNow Autonomous data is reliable up to 3 days after initial capture.<\/p>\n<p><strong>Protocols and interfaces<\/strong><\/p>\n<p>Protocol\u00a0<strong>type<\/strong><\/p>\n<p>INPUT\/Output NMEA, ASCII, 0183, 2.3 (compatible with 3.0) UBX input\/output, binary, u-blox patented RTCM input, 2.3<\/p>\n<p><strong>UART<\/strong><\/p>\n<p>GT-U7 modules include a configurable UART interface for serial communication.<\/p>\n<p><strong>USB<\/strong><\/p>\n<p>GT-U7 modules provide a USB version 2.0 FS interface (full speed, 12 Mbit\/s) as an alternative to the UART. Pull-up resistance in USB_DP integrated to signal a full-speed device to the host. The VDDUSB pin supplies the USB interface. u-blox provides a Microsoft-certified USB driver\u00ae for Windows XP, Windows Vista, and Windows 7 operating systems.<\/p>\n<p><strong>Serial Peripheral Interface (SPI) The<\/strong><\/p>\n<p>SPI interface allows the connection of external devices with a serial interface, p. E.g. flash serial to save AssistNow Offline A-GPS settings and data or to connect to a host CPU. The interface can be operated in master or slave mode. In master mode, a chip selection signal is available for selecting external slaves. In slave mode, a single chip selection signal allows communication with the host.<\/p>\n<p><strong>Power management<\/strong><\/p>\n<p>U-blox receivers support different power modes. These modes represent strategies of how to control acquisition and tracking engines in order to achieve the best possible performance or good performance with reduced power consumption.<\/p>\n<p><strong>Maximum performance mode During<\/strong><\/p>\n<p>a cold start, a receiver in maximum performance mode continuously deploys the acquisition engine to search for all satellites. Once the receiver has a fixed position (or if pre-positioning information is available), the acquisition engine is still used to search for all visible satellites that are not being tracked.<\/p>\n<p><strong>Eco-mode<\/strong><\/p>\n<p>During a cold start, a receiver in Eco mode works exactly as in maximum performance mode. Once a position can be calculated and a sufficient number of satellites are being tracked, the acquisition engine shuts down, resulting in significant energy savings. The tracking engine continuously tracks purchased satellites and acquires other available or emerging satellites.<\/p>\n<p><strong>Power-saving mode<\/strong><\/p>\n<p>Power saving mode (PSM) allows a reduction in system power consumption by turning receiver parts on and off.<\/p>\n<p><strong>Lora Module<\/strong><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm.jpg\"><img loading=\"lazy\" class=\"alignnone wp-image-6123 size-medium\" src=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-300x300.jpg 300w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-150x150.jpg 150w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-768x768.jpg 768w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-1024x1024.jpg 1024w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-600x600.jpg 600w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm-820x820.jpg 820w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/12\/lora-drf1276dm.jpg 1200w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<h4>About Lora Modules<\/h4>\n<div class=\"desCon\">\n<p>The LoRa radio module is a type of low-speed long-range data radio modem based on Semtech’s Sx1276. It is a low cost transceiver module of less than 1 GHz designed for operations in the ISM (Industrial Scientific Medical) and LPRD bands without license. Frequency spectrum modulation\/demodulation, multichannel operation, high bandwidth efficiency and anti-lock performance make LoRa modules easy to perform thanks to robust and reliable wireless linking.<\/p>\n<div class=\"desCon\">\n<p>The module can operate in two different modes: standard mode and Star network mode. In standard mode, it acts as a transparent data radio modem that communicates with the host in the preset data format without the need for encoding\/decoding. In startup network mode, a module will be configured for the central node and other modules will be configured as node modules. Communication between the central module and the node module is bidirectional, but node modules cannot communicate with each other. Note that the module does not contain the lorawan protocol. Therefore, the star network function of this module is used with the protocol itself, so it is not compatible with lorawan.<\/p>\n<\/div>\n<div>\n<h4>Features<\/h4>\n<div class=\"desCon\">\n<ul>\n<li>LoRa Frequency Spectrum<\/li>\n<li>Frequency band 433 \/ 490Mhz ISM<\/li>\n<li>-137 dBm receive sensitivity<\/li>\n<li>20 dBm max. output power<\/li>\n<li>Serial activation port<\/li>\n<li>Wireless alarm clock<\/li>\n<li>Star network capacity<\/li>\n<li>Supply voltage 3.4 x 5.5V<\/li>\n<\/ul>\n<h4>Specification<\/h4>\n<div class=\"desCon\">\n<ul>\n<li>Operating Voltage: 2.1 x 3.6V (Battery Powered) or 4.5×5.5V<\/li>\n<li>Working frequency band: 433 MHz<\/li>\n<li>Modulation: LoRa extended spectrum<\/li>\n<li>Output power: \u2264 20dBm<\/li>\n<li>Reception sensitivity: -148dBm<\/li>\n<li>Emission current: \u2264120mA<\/li>\n<li>Receiving current: \u226415.2mA<\/li>\n<li>Sleep current: \u2264 3.9uA<\/li>\n<li>Sleep time: optional 2S, 4S, 6S, 8S, 10S<\/li>\n<li>Breathing time: optional 2ms, 4ms, 8ms, 16ms, 32ms, 64ms<\/li>\n<li>Time to wake up: wake up immediately<\/li>\n<li>Communication interface: TTL serial communication<\/li>\n<li>Serial transmission speed: 1200 x 57600,9600bps (default)<\/li>\n<li>Serial port verification: 8E1.8O1.8N1 (optional)<\/li>\n<li>Operating temperature: -40oC \u2013 + 80oC<\/li>\n<li>Product size: 34.2 * 18.4mm \/ 1.35 * 0.72 inch<\/li>\n<\/ul>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1.jpg\"><img loading=\"lazy\" class=\"alignnone wp-image-4866 size-medium\" src=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1-300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1-300x200.jpg 300w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1-768x512.jpg 768w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1-600x400.jpg 600w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1-820x547.jpg 820w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora1.jpg 900w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora2.jpg\"><img loading=\"lazy\" class=\"alignnone wp-image-4867 size-full\" src=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora2.jpg\" alt=\"\" width=\"564\" height=\"376\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora2.jpg 564w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/lora2-300x200.jpg 300w\" sizes=\"(max-width: 564px) 100vw, 564px\" \/><\/a><\/p>\n<h4>Data Sheets<\/h4>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/DRF1276DM.pdf\">DRF1276DM<\/a><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/DRF1278DM.pdf\">DRF1278DM<\/a><\/p>\n<p><strong>PIN OUT<\/strong><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/pin_out.png\"><img loading=\"lazy\" class=\"alignnone wp-image-4888 size-medium\" src=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/pin_out-300x272.png\" alt=\"\" width=\"300\" height=\"272\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/pin_out-300x272.png 300w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/pin_out.png 362w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<h4>Connection Module with Serial USB adapter<\/h4>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2.png\"><img loading=\"lazy\" class=\"alignnone wp-image-4880 size-large\" src=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-1024x576.png\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-1024x576.png 1024w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-300x169.png 300w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-768x432.png 768w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-600x338.png 600w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-820x461.png 820w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2-1320x743.png 1320w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2019\/08\/Imagen2.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<p><strong>SETTINGS<\/strong><\/p>\n<p>For some applications, default parameters may not be the best<\/p>\n<p>option, so users may need to change the parameters There are two ways to adjust them: by MCU or by PC.

For the central module, it works<\/p>\n<p>at full performance so its power consumption is<\/p>\n<p>the same as in standard mode and the EN pin must be connected to the low logic. The logical level of the<\/p>\n<p>SET pin for the central module must be the same as the node module.<\/p>\n<hr \/>\n<\/div>\n<p>You may be interested in projects in Arduino, pic, robotics, telecommunications,\u00a0<a href=\"http:\/\/www.youtube.com\/user\/carlosvolt?sub_confirmation=1\">subscribe http:\/\/www.youtube.com\/user\/carlosvolt?sub_confirmation=1<\/a>\u00a0videos with full source code and diagrams<\/p>\n<div id=\"ubm-banners-rotation-n2\" class=\"ubm_banners_rotation\" data-interval=\"4000\">\n<div id=\"3_ubm_banner\" class=\"ubm_rotating_banner\"><div id=\"ubm-banners-rotation-n2\" data-interval=\"4000\" class=\"ubm_banners_rotation\" style=\"overflow: hidden;
