BLE 2 Click Board™

Product Code: MIKROE-1715

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).
