nRF24AP2-USB Product Specification

2.4.1

Power supply pins

VBUS and VSS are the power supply and ground pins. The nRF24AP2-USB can operate from a single

power supply.

The nRF24AP2-USB contains an on-chip regulator that produces +3.3V on the VDD pins, from the VBUS

supply line (4.0 – 5.25V). Alternatively, the VBUS pin can be left open and the VDD pins may be fed from an

external 3.3V supply. In this case, the on-chip 3.3V regulator is switched off.

2.4.2

Reset pin

The RESET pin provides an optional reset when the nRF24AP2-USB is placed in a system that has a

master reset source, this pin is not needed for normal application. Pull RESET pin low for minimum 0.2 μs

and return to high, this will reset the nRF24AP2-USB to the default state. Connect RESET pin to VDD if not

used in the application.
