# Title: BLE 2 Click Board™


## Description: The BLE2 Click Board™ is an excellent choice if you want simple, temporary connectivity with your smart devices over Bluetooth 4.1. The BLE2 Click Board™ features the RN4020 module from Microchip, which integrates RF, a baseband controller, and a command API processor, making it a complete Bluetooth Low Energy solution. The click communicates with the target board MCU through mikroBUS™ RX, TX and AN (CMD), PWM (con.), and RST (wake) lines. The board is designed to use a 3.3V power supply only. Microchip Low-energy Data Profile The RN4020 has Microchip's Low-energy Data Profile (MLDP) which enables an asynchronous serial data connection between two RN4020 devices (which could be two BLE2 Click Board™s). The module can be remotely controlled or updated over the air by another module over a secure connection or can be controlled or updated through its UART interface. PCB trace Antenna The RN4020 module aboard BLE2 click incorporates a PCB antenna with a range of at least 30m. Bluetooth 4.1 Bluetooth 4.1 is intended for IoT, it has low power consumption and lets any device be a peripheral and a hub at the same time. Specifications Type BT/BLE Applications Bluetooth Low Energy is becoming a pervasive standard for IoT applications in any number of domains (home automation, fitness, health and so on).

<h3>Microchip Low-energy Data Profile</h3>

<p>The RN4020 has <strong>Microchip's Low-energy Data Profile</strong> (MLDP) which enables an asynchronous serial data connection between two RN4020 devices (which could be two <strong>BLE2 Click Board™</strong>s). The module can be remotely controlled or updated over the air by another module over a secure connection or can be controlled or updated through its UART interface.</p>

<h3>PCB trace Antenna</h3>

<p>The RN4020 module aboard BLE2 click incorporates a PCB antenna with a range of at least <strong>30m</strong>. </p>

<h3>Bluetooth 4.1</h3>

<p><strong>Bluetooth 4.1</strong> is intended for IoT, it has low power consumption and lets any device be a peripheral and a hub at the same time.</p>

- amazon_long_description: <h3>IC/Module: RN4020 Bluetooth 4.1 module</h3><p>RN4020 is a high performance, fully qualified Bluetooth Version 4.1 module intended to easily add low power wireless capability to the device. The compact size favours easy integration in size-constrained applications. This surface mount module has complete Bluetooth stack on-board and can be remote controlled by another module over a secure connection.</p><h3>MLDP Support</h3><p>The two RN4020 Bluetooth modules, when used in a pair, make a powerful combination due to MLDP support. MLDP enables connecting a pair of BLE2 Clicks easy and quick.</p><h3>Embedded PCB antenna</h3><p>The module with an on-board PCB antenna gives you a range of about 30 meters, when tested in closed space. However, it is possible to get a better range depending on the conditions.</p><h3>Communication Lines</h3><p>BLE2 Click communicates with the target board MCU through mikroBUS RX, TX and AN (CMD), PWM (CON), and RST (WAKE) lines.</p>

- summary: <p>The <strong><em>BLE 2 Click Board™</em></strong> is an excellent choice if you want simple, temporary connectivity with your smart devices over Bluetooth 4.1.<br></p>
<p>The <strong>BLE 2 Click Board™</strong> features the RN4020 module from Microchip, which integrates RF, a baseband controller, and a command API processor, making it a complete Bluetooth Low Energy solution. The Click Board™ communicates with the target board MCU through MikroBUSRX, TX and AN (CMD), PWM (con.), and RST (wake) lines. The board is designed to use a 3.3V power supply only.</p>
