RN4870/71 Bluetooth 4.2 Low Energy Module Features Fully Qualified Bluetooth Smart Module On-Board Bluetooth 4.2 Low Energy Stack ASCII Command Interface API over UART Scripting Engine for Hostless Operation Compact Form Factor The RN4870/71 family comes in four different sizes from 6 mm x 8 mm to 12 mm x 22 mm: - RN4870: 12 mm x 22 mm - RN4871: 9 mm x 11.5 mm - RN4870U: 12 mm x 15 mm - RN4871U: 6 mm x 8 mm Beacon Private Service for Beacon Services UART Transparent Service for Serial Data Applications Remote Configuration Over The Air Operational Operating Voltage: 1.9V to 3.6V (3.3V typical) Temperature Range: -20C to +70C Supports UART Up to Three Pulse Width Modulation (PWM) Outputs RF/Analog Features ISM Band 2.402 to 2.480 GHz Operation Channels: 0-39 Description RX Sensitivity: -90 dBm The RN487x modules, based on Microchip s IS187x TX Power: 0 dBm Bluetooth LE ICs, provide a complete solution to RSSI Monitor implement Bluetooth 4.2 Low Energy connectivity. MAC/Baseband/Higher Layer Features These modules are interfaced via a two- or four-wire Secure AES128 Encryption UART interface with Microchip s simple ASCII GAP, GATT, SM, L2CAP and Integrated Public command set for easy integration into most Profiles applications. All products in the RN series can be Customer Can Create up to Five Public and Four dynamically configured by the host microcontroller with Private Services a few simple ASCII commands. The RN487x series Keyboard I/O Authentication also supports on-board scripting to automate basic Software Configurable Role as Peripheral or operations without a host microcontroller. The RN4870 Central and Client or Server (12 mm x 22 mm) and RN4871 (9 mm x 11.5 mm) modules combine Microchip s Bluetooth LE Silicon with Antenna Options all necessary peripheral components and an on-board Ceramic Chip Antenna (RN4870/RN4871) chip antenna to create an easy to use/drop-in solution. External Antenna Connection via RF pad All modules in this series are Bluetooth SIG qualified. (RN4870U/RN4871U) The RN4870 and RN4871 include FCC modular Applications certification, as well as most other worldwide Health/Medical Devices government regulatory approvals.
