The integrated Bluetooth Low Energy (BTLE) stack and support for the most common low-energy GIS profiles accelerate time to market, ensure Bluetooth compatibility, eliminate high certification costs, and reduce development risks. The module also comes pre-loaded with the Microchip Low-energy Data Profile (MLDP), allowing designers to easily input any type of data via the BTLE link.
The RN4020 is a stack-on-board module, so it can be connected to any microcontroller with a UART interface, including hundreds of PIC® microcontrollers, or it can operate independently without a microcontroller for basic data collection and communication, such as in a beacon or sensor. This independent operation is facilitated by Microchip's unique no-compilation programming, which allows the module to be configured using a simple ASCII instruction interface, without the need for tools or compilation.
Cost-conscious embedded application designers are seeking comprehensive solutions that facilitate the integration of low power consumption and the simplicity of Bluetooth LE connectivity, which enables years of operation on a single battery and boasts a large installed base of compatible smartphones, tablets, and computers. Markets requiring these low-power wireless command and control solutions include home and appliance automation; medical and wearable devices; toys, tags, key fobs, and remote controls; sensor-based pulse and proximity systems; and even industrial applications.
The Microchip RN4020 Bluetooth LE Smart module includes all the hardware, software, and certifications designers need to easily add low-power connectivity to any design, simplifying the final product list through Bluetooth QDID compatibility testing. All programmable profiles are stored and selectable on the module, including Microchip's flexible MLDP and the most common Bluetooth SIG low-power profiles. In addition to the most common public profiles, custom services can be created using the ASCII instruction interface. The RN4020 also incorporates an on-board antenna with a transmit power of 7 dBm and a receive sensitivity of -92.5 dBm, enabling a range of over 100 meters* in a compact form factor of only 11.5 x 19.5 x 2.5 millimeters.
Microchip has also announced a development board, the RN4020 Bluetooth Low Energy PICtail™/PICtail Plus Flexible Daughterboard (RN-4020-PICtail), which is available now for $49. This board enables code development via a USB interface to a PC and through the built-in In-Circuit Serial Programming™ for Microchip's PICkit™ or MPLAB® REAL ICE™ tools. It also allows customers to leverage their existing investments in Microchip's PICtail-compatible development boards, such as the Explorer 16, PIC18 Explorer, and PIC32 I/O Expansion Board. Furthermore, the built-in eXtreme Low Power (XLP) PIC18 microcontroller allows the PICtail board to operate in standalone mode, powered via USB from the host, as well as for demonstrations and proof-of-concept testing.
The RN4020 Bluetooth Low Energy module is now available. This module, certified to global standards and by the Bluetooth SIG, measures 11.5 x 19.5 x 2.5 millimeters and incorporates an antenna on the board.
