MIKROE BLE 4 Click

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.
