Block diagram: General Purpose I/O: The general purpose I/O is organized as one port enabling access and control of the 32 available GPIO pins through one port. Each GPIO can be accessed individually with the following user configurable features: Input/output direction Output drive strength Internal pull-up and pull-down resistors Wake-up from high or low level triggers on all pins Trigger interrupt on all pins All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels All pins can be individually configured to carry serial interface or quadrature demodulator signals HW debug and flash programming of Module: The Module support the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanism for non -intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support. Pin Flash Program interface SWDIO Debug and flash programming I/O SWCLK Debug and flash programming I/O This is the hardware debug and flash programming of module, J -Link Lite support, please refer www.segger.com.

PCB Layout（TOP VIEW）: Recommended RF Layout & Ground Plane: The module integrated antenna requires a suitable ground plane to radiate effectively. The area under and extending out from the antenna portion of the module should be kept clear of copper and other metal. The module should be placed at the edge of the PCB with the antenna edge facing out. Reducing the ground plane will reduce the effective radiated power.
