Product Description
Microchip’s RN4020 is a fully certified Bluetooth Version 4.1 low energy module that enables you to add low power wireless capability to your products with ease.
The surface mount module boasts a small form factor (11.5 x 19.5 x 2.5mm) and is controlled via simple ASCII commands over the UART interface. It features the complete Bluetooth stack on-board.
The RN4020 also includes all Bluetooth SIG profiles, as well as MLDP (Microchip Low-energy Data Profile) for custom data. The scripting feature enables standalone operation without a host MCU or Processor. It can be remote controlled by another module over a secure connection and can be updated via the UART interface or over the air.
The module’s built-in high performance PCB antenna has a range typically over 100 metres. The RN4020 can be used with any low cost microcontroller for intelligent Bluetooth Low Energy applications.
It is a true drop-in solution that is easy to use and easy to prototype, greatly speeding time to market.
