ABLUE TECHNOLOGY   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 Hardware RESET: There is on-chip power-on reset circuitry, But can still be used in external reset mode, in this case, GPIO pin P0.18 as an external hardware reset pin. In order to utilize P0.

ABLUE TECHNOLOGY USB Power: The USB interface on the Module can be used when the module is in either Normal /Low Voltage (LV) or High Voltage (HV) mode. The Module USB PHY is powered by a dedicated, internal LDO regulator that is fed by the VBUS pin (Pin43). This means that applying power to only the VBUS pin will not power the rest of the module. In order for the USB PHY to operate, VBUS must be externally powered.

ABLUE TECHNOLOGY 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.

ABLUE TECHNOLOGY Moisture Sensitivity All plastic packages absorb moisture. During typical solder reflow operations when SMDs are mounted onto a PCB, the entire PCB and device population are exposed to a rapid change in ambient temperature. Any absorbed moisture is quickly turned into superheated steam. This sudden change in vapor pressure can cause the package to swell. If the pressure exerted exceeds the flexural strength of the plastic mold compound, then it is possible to crack the package.
