  • RN4678 click - MikroElektronika Bluetooth 4.2 Dual Mode Module

    RN4678 click carries the RN4678 Bluetooth® 4.2 dual mode module from Microchip. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over I2C and UART interface, with additional functionality provided by the following pins on the mikroBUS™ line: AN, RST, CS, PWM, INT.

    RN4678 module features

    The RN4678 from Microchip is a fully certified, Bluetooth version 4.2 module. Use it to add Bluetooth wireless capability to your project.

    The module includes an on-board Bluetooth stack, power management subsystem, 2.4 GHz transceiver, and RF power amplifier.

    Data transfer is achieved through the Bluetooth link by sending or receiving data through SPP in Bluetooth (BT) Classic mode and through Transparent UART in the BLE mode.

    The RN4678 contains an integral ceramic chip antenna.

    Strong encryption

    The RN4678 module has strong AES128 Encryption. A 128-bit encryption is one of the most powerfull encryption algorithms. AES stands for Advanced Encryption Standard and it is a symmetric encryption algorithm.
