RN4871 Click carries the RN4871 Bluetooth® 4.2 low energy module from Microchip. The Click is designed to run on a 3.3V power supply. It uses ASCII Command Interface over UART for communication with target microcontroller, with additional functionality provided by the following pins on the mikroBUS™ line: RST, CS, and INT.

RN4871 MODULE FEATURES

The RN4871 Bluetooth Low Energy module integrate Bluetooth 4.2 baseband controller, on-board Bluetooth stack, digital and analog I/O, and RF power amplifier into one solution.

The module contains an integral ceramic chip antenna.

All products in the RN series can be dynamically configured by the host microcontroller with a few simple ASCII commands.

The RN4871 supports both peripheral and central Generic Access Profile (GAP) roles, actively scanning for other connectable devices instead of waiting for incoming connection requests. The peripherals are usually small, low power devices like sensors and monitors, that broadcast information to the central device. The central device can communicate with multiple peripherals.
