Description
Microchip’s RN4020 Bluetooth Low Energy Module pro-
vides a highly integrated solution for delivering low-power
Bluetooth 4.1 solutions. The advanced command inter-
face offers rapid time to market. The RN4020 module
complies with Bluetooth specification version 4.1. The
module integrates RF, a baseband controller, and a com-
mand API processor, making it a complete Bluetooth Low
Energy solution. The RN4020 can be used with ultra-low
cost microcontroller for intelligent Bluetooth Low Energy
applications. For simple sensor applications, the RN4020
internal scripting capabilities enable basic functions to be
implemented without the need for external host MCU or
software development tools.
