    • RN4020 Bluetooth Low Energy PICtail/PICtail Plus Daughter Board


    The RN4020 PICtail / PICtail Plus Board is a Bluetooth Low Energy demonstration board that showcases the Microchip RN4020 module, a fully-certified Bluetooth Version 4.1 low energy module for designers who want to easily add low power wireless capability to their products. This flexible development board includes the RN4020 paired with an eXtreme Low Power PIC18F25K50 microcontroller.

    This convenient development board includes a USB to UART interface for plug-and-play capability. The high-speed UART interface and the General Purpose Input Output (GPIO) ports are available on the RN4020 module to configure, control and transfer data. The RN-4020-PICtail also includes PICtail and PICtail Plus interfaces for connecting to Microchip development boards. The on-board PIC18 microcontroller can be custom programmed via the available PICkit serial programmer / debugger interface. The board also includes on-board connection and data status LEDs enabling rapid prototyping and fast time to market.

    Note: Ensure that the PICtail connector pin-out on the host MCU development platform supports the pin-out on the PICtail interface on the RN4020 PICtail Plus Daughter Board
