The RN4871-V/RM118 is a Bluetooth 4.2 low energy module. The RN4871 module is based on Microchip's IS1871 Bluetooth LE ICs, provide a complete solution to implement Bluetooth 4.2 low energy connectivity. This module is interfaced via a two or four wire UART interface with Microchip's simple ASCII command set for easy integration into most applications. The RN series can be dynamically configured by the host microcontroller with a few simple ASCII commands. The RN4871 also supports on-board scripting to automate basic operations without a host microcontroller. The RN4871 (9mm x 11.5mm) module combines Microchip's Bluetooth LE Silicon with all necessary peripheral components and an on-board chip antenna to create an easy to use/drop-in solution. The module is Bluetooth SIG qualified. The RN4871 includes FCC modular certification, as well as most other worldwide government regulatory approvals.
