They should be connected to Host board GND net. Signal name: GPIO_X Pin number(s): 2-6 These pins are used as general purpose IO.
2011-06-29 NUR-05W Implementation Guide v0.7 CONFIDENTIAL Signal name: USB_DET Pin number(s): 12 This pin is used only for USB connection detection. It is advised to use external ESD protection component if connected to user accessible USB connector. Current is not drawn from this input pin. Signal name: +3V3 Pin number(s): 13 Pin is connected to internal regulator output. Pin is used for production testing and it can be left unconnected.
2011-06-29 NUR-05W Implementation Guide v0.7 CONFIDENTIAL 4 4.1 DESIGN CONSIDERATIONS RF output and antenna recuirement RF output impedance is 50Ω so it is important to keep the trace leaving from RF_OUT pin in that same impedance level to avoid reflections and mismatch of RF signal. It is recommended to do copper pour keep out area to Host board top layer according to picture below. Other layers can be filled with copper. Recommended host board copper keep out area.
2011-06-29 NUR-05W Implementation Guide v0.7 CONFIDENTIAL 4.3 USB device port USB_DP, USB_DN and USB_DET pins are used to provide 2.0 compliant USB device port. It must be remembered that only one communication method can be used to communicate with NUR-05W module at the time. Connecting USB will automatically prevent communication via serial port. It is advised to use external ESD protection component if connected to user accessible USB connector.
2011-06-29 NUR-05W Implementation Guide v0.7 CONFIDENTIAL 5 5.1 RF PARAMETERS Output power Maximum output power is +27dBm (500mW). Power can be adjusted by 1dB steps. There is 19 steps so minimum output value is 8dBm what equals 6mW power. When using high output power it must be remembered that then antennas VSWR comes even more important. Because high output power combined with antenna with poor VSWR means that lot of power is reflected back to receiver. 5.
2011-06-29 NUR-05W Implementation Guide v0.7 CONFIDENTIAL 5.5 RX coding (miller coding) Like stated above miller coding scheme affects also tag to reader data rate. In practice miller coding affects the number of clock cycles that tag uses to modulate one symbol. So when using higher Miller coding scheme tag to reader data rate will be slower but at the same time it is more robust to interferences. Also tags response spectrum is more concentrated around the link frequency when using high miller scheme.
