Product information "NB IoT 5 Click"

NB IoT 5 Click is a compact add-on board suitable as narrow-band Internet of Things universal wireless communication solution. This board features the OT01-5, a high-performance NB-IoT module with ultra-low power consumption allowing battery life of about ten years from Notion. It supports a broad range of frequency bands almost worldwide. It provides serial interfaces, UART and SPI, with protocol stacks such as UDP/TCP, CoAP, LWM2M, and others. It is offering an alternative to similar Low Power Wide Area Network (LPWAN) solutions. This Click board™ is suitable for a wide range of IoT applications such as smart gas/water meters, information collection, security monitoring, smart city/home, and other applications.

NB IoT 5 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

NOTE: Please use an antenna that supports frequency bands used by the Notion OT01-5 module to ensure the best performance.

NB IoT 5 Click as its foundation uses the OT01-5, a high-performance narrow-band Internet of Things universal wireless communication module with extremely low power consumption allowing battery life of about ten years from Notion. It supports a broad range of frequency bands worldwide, such as 1 / 2 / 3 / 5 / 8 / 19 / 20 of 3GPP R13 (NB1) and R14 (NB2). It also provides several interfaces, UART and SPI, and protocol stacks such as UDP/TCP, CoAP, LWM2M, and others. In addition to motor driver inside-design, these protocols allow data and SMS transfer using the NB technology and make this module a perfect choice for building IoT applications and smart gas and water meters without an external microcontroller unit.

There are two ways to turn on this Click board™, through EN pin on the mikroBUS™ socket or by pressing the PWRKEY button down for a period longer than 3 seconds. The onboard push-button labeled as PWRKEY routed to the PWM pin on the mikroBUS™ socket represents the Ignition (Power-On) button. This feature is shown by the yellow diode labeled as STAT used to indicate the device's Operational Status.

NB IoT 5 Click communicates with MCU using the UART interface as its default communication protocol with the option for the users to use another interface such as SPI, if they want to configure the module and write the library by themselves. It supports automatic baud rate detection, operates at 115200 bps by default configuration, and is used for data transmission and exchanging AT commands with the host MCU. Also, it has an additional header used for firmware upgrades, software debugging, log capturing, or even as a motor drive.

In addition to these features, the OT01-5 also uses several GPIO pins connected to the mikroBUS™ socket. The WUP pin routed on the AN pin of the mikroBUS™ represents the Wake-up function used for waking up the device, while the RST pin on the mikroBUS™ socket can perform Hardware Reset function by putting this pin in a logic low state. This Click board™ also has the micro USB connector allowing the module to be powered and configured by a personal computer.

NB IoT 5 Click possesses the SMA antenna connector with an impedance of 50Ω. This Click board™ can use it to connect the appropriate antenna, such as LTE Flat Rotation Antenna, that Mikroe has in its offer. Besides the SMA connector, it also has a Nano-SIM card slot that provides multiple connections and interface options.

This Click board™ can operate with both 3.3V and 5V MCUs set via jumper labeled as VCC SEL with a proper logic voltage level conversion performed by the appropriate voltage level translator TXS0108E. This way, it is allowed for both 3.3V and 5V capable MCUs to use communication lines properly. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
