BLE 4 Click is fully embedded stand-alone Bluetooth 5.0 low energy connectivity module, equipped with the NINA-B312, an ultra-small, high-performing, standalone Bluetooth low energy module for easy integration of Bluetooth low energy connectivity (BLE) into various electronic devices. This module combines a high-performance Arm® Cortex®-M4 CPU microprocessor with FPU, and state-of-the-art power performance. Reliable and easy to use, BLE 4 Click is a perfect solution for development of various IoT applications, smart home applications, BLE enabled toys, advanced robotics, and other similar applications.
BLE 4 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
BLE 4 Click is a Click board™ which provides Bluetooth Low Energy connectivity for any embedded application. It features the NINA-B312, an integrated wireless connectivity solution. The NINA-B312 module itself is based on the nRF52840 chip, a flexible, efficient Bluetooth 5 and Bluetooth mesh multiprotocol SoC. Armed with such a powerful processor, the NINA-B312 can achieve data rates of up to 2 Mbps and up to 5 dBm maximum radiated output power using internal antenna, ensuring a reliable connection and good signal coverage. BLE 4 Click is ideal for small smart devices like home automation sensor and fitness applications that need to require really low power consumption and long battery life.
BLE 4 Click is equipped with the NINA-B312, Stand-alone Bluetooth 5 low energy module by u-blox, which is based on the nRF52840 chip. The nRF52840 is the mid-range member of the nRF52 Series SoC family. It meets the challenges of a broad range of applications that need Bluetooth 5 feature sets, protocol concurrency and a rich and varied set of peripherals and features. In addition, it offers generous memory availability for both Flash and RAM. It is operated by a set of AT commands, over the UART interface, which makes the BLE 4 Click very easy to use.
By integrating most of the critical components on the chip, the NINA-B312 allows the module to overcome any imperfections of external discrete components, allowing signal transmission power of up to 10dBm, and -94 dBm sensitivity for the receiver, using the on-chip antenna.
The NINA-B312 module is built around an ARM® Cortex™-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag for use in simplified pairing and payment solutions, as well as numerous digital peripherals and interfaces such as PDM. Therefore, BLE 4 Click has the onboard 2-pin header, that can be used for connecting the optional NFC antenna. It is also fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth 5, Bluetooth mesh, and 2.4 GHz proprietary stacks.
Besides the mikroBUS™ socket, BLE 4 Click also features two onboard buttons T1 and T2. These buttons can be used for various purposes and user programmable. This Click board™ also has an onboard user programmable RGB LED - LD2, which in combination with the mentioned buttons can be used for various purposes for basic user interaction without any external components required besides the BLE 4 Click.
This Click board™ is designed to be operated only with 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
