Microchip Technology Inc. has debuted its first Bluetooth 4.1 Low Energy module. According to the company, the RN4020 builds on its deep Bluetooth Classic experience and carries both global regulatory certifications and is Bluetooth Special Interest Group (SIG) certified.

The integrated Bluetooth Low Energy (BTLE) stack and on-board support for the common SIG low-energy profiles speeds time to market while ensuring Bluetooth compatibility, eliminating expensive certification costs and reducing development risks. The module is also pre-loaded with the Microchip Low-energy Data Profile (MLDP), which enables designers to easily stream any type of data across the BTLE link.


Because the RN4020 is a stack-on-board module, it can connect to any MCU with a UART interface, including hundreds of PIC MCUs, or it can operate standalone without an MCU for basic data collection and communication such as a beacon or sensor. This standalone operation is facilitated by Microchip's unique no-compile scripting, which allows module configuration via a simple ASCII command interface, no tools or compiling are required.

Microchip's RN4020 Bluetooth LE Smart module includes all of the hardware, software and certifications that designers need to easily add this low-energy connectivity to any design, while easing End Product Listing (EPL) via QDID Bluetooth compatibility testing. All of the programmable profiles are stored and selectable on the module, including Microchip's flexible MLDP and the common Bluetooth SIG low-energy profiles. In addition to common public profiles, private services can be created via the ASCII command interface. The RN4020 also provides a built-in PCB antenna with 7dBm transmit power and a receive sensitivity of -92.5dBm, enabling operation over 100m.

The RN4020 Bluetooth Low Energy module is available in 1,000-unit quantities. The module measures 11.5 x 19.5 x 2.5mm, and includes a built-in PCB antenna.
