Das 4G LTE 2 Data Click Board™ ist eine kompakte Zusatzplatine, die eine sichere Cloud-Multibandlösung mit universeller Konnektivität und zuverlässiger Leistung darstellt. Diese Platine verfügt über das LARA-R6001D, das weltweit kleinste LTE Cat 1-Modul mit globaler Abdeckung und einem integrierten MQTT-Client von u-blox, der eine reine Datenlösung darstellt. Ausgestattet mit bekannten AT-Befehlen über die UART-Schnittstelle, USB-Schnittstelle und Netzwerk- und Statusanzeigen verfügt das LARA-R6001D außerdem über ein umfassendes Zertifizierungsschema sowie Multiband- und Multimode-Funktionen, die hervorragende Flexibilität bieten, mit Ausnahme der Unterstützung von Sprach-/Audioanwendungen. Dieses Click Board™ nutzt eingebettete IoT-Protokolle und Sicherheitsfunktionen und eignet sich für verschiedene Anwendungen wie Geräteverwaltung, Remote-Geräteaktionen und sichere FOTA-Updates.
Das 4G LTE 2 Data Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ ist ein gründlich getestetes Produkt und kann auf einem System verwendet werden, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The 4G LTE 2 Click Board™ Work?
The 4G LTE 2 Click Board™, as its foundation, uses the LARA-R6001D, a multi-band and multi-mode module supporting LTE Cat 1 FDD and LTE Cat 1 TDD radio access technology (18 LTE bands), with 3G UMTS/HSPA and 2G GSM/GPRS/EGPRS fallback from u-blox providing the ideal solution for uncompromised global connectivity. This Click board™ represents a data-only solution with global coverage and all relevant MNO certifications, offering great flexibility except for the support of voice/audio applications. Versatile interfaces and features make the LARA-R6001D ideally suited for a wide range of applications that require medium data speed, seamless connectivity, superior coverage, low latency, and streaming data such as asset tracking, telematics, remote monitoring, point-of-sale terminals, and more.
This module requires a power supply of 3.8V. Therefore, the Click board™ incorporates an integrated buck (step-down DC-DC) converter, labelled as TPS7A7002 by Texas Instruments, which provides a stable 3.8V power supply, capable of mitigating voltage drops at the input when a high current peak appears (typically at the StartUp of the device). The module Ignition (Power-On) pin, labelled as PWR and routed to the RST pin on the mikroBUS™ socket, offers a switch operation to turn ON/OFF power delivery to the LARA-R6001D.
The LARA-R6001D communicates with MCU using the UART interface with commonly used UART RX and TX pins with the hardware flow control pins UART CTS, RTS, RI (Clear to Send, Ready to Send, and Ring Indicator). It operates at 115200 bps by default configuration to transmit and exchange data with the host MCU through AT commands that u-blox provides. Besides the UART interface, the LARA-R6001D also provides the possibility of using the I2C interface acting as an I2C host, which can communicate with I2C local devices following the I2C bus specifications. The 4G LTE 2 Click Board™ is also equipped with a USB type C connector, available for diagnostic purposes only. The module is a USB device and can be connected to any USB host with compatible drivers.
Among its used pins, this Click board™ also possesses two additional LED indicators: the yellow LED labelled as STATUS, routed both to the mikroBUS™ AN pin (STS) and the LED, used to indicate the status of the network connection visually, and a red LED labelled as TX used to tell the transmitting status of the module.
The LTE cellular networks use spatial multiplexing antenna technology, allowing more than one antenna to be used for better reception of the specific frequency channel. For that reason, besides the primary TX/RX antenna, this Click board™ uses a secondary diversity RX antenna, which allows better signal reception. Alongside those SMA connectors, the 4G LTE 2 Click also has a Nano-SIM card slot that provides multiple connections and interface options alongside several test points labelled from TP1 to TP3, enabling easy reboot and testing of the module.
The 4G LTE 2 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
