Description
Microchip's RN4020 Bluetooth Low Energy Module
provides a highly integrated solution for delivering low
power Bluetooth 4.1 solu tions. The advanced com-
mand interface offers rapid time to market.
The RN-4020 module complies with Bluetooth specifi-
cation version 4.1. It integrates RF, a baseband control-
ler, command API processor, making it a compl ete
Bluetooth Low Energy Solution.
The RN4020 can be use d with ei ther low cost micro-
controller for intelligent Bluetooth Low Energy applica-
tions. For simpl e sensor ap plications, the RN4020
internal scripting capabilities enable basic functions to
be implemented without the need for external host
MCU or software development tools.
