Network and Communication Chips from RS Components, Ltd.



The RN4870 module is based on the IS187x Bluetooth device and provides a complete solution to implement Bluetooth 4.2 Low Energy connectivity. The module is interfaced to a host MCU via a UART serial port using Microchip’s ASCII command set for easy integration into most applications. The module can be dynamically configured by the host MCU with a few simple ASCII commands. The RN4870 also supports on-board scripting to automate basic operations enabling it to stand alone without a host microcontroller.
