Table 1: xPico Wi-Fi Embedded Device Server Components  
					Component  
					Description  
					xPico Serial Number  
					Also the module MAC Address. The last six digits are used in the  
					default SSID for Soft AP mode.  
					u.FL Socket  
					Used to connect either the SMA antenna cable or the alternative  
					PCB strip antenna to the xPico Wi-Fi Module.  
					SMA  
					SW3  
					J5  
					If using External antenna attach at this point.  
					Power switch, turns power on and off to the Evaluation PCB.  
					Mini-USB socket used for connecting power to the Evaluation Kit or  
					to connect to the xPico module serial port 2 via an on-board USB to  
					serial converter  
					JP19 (pin 1 +, pin 2 GND)  
					Battery Port (2.2 to 5.5V) provides power to the xPico Wi-Fi Module  
					via on board DC to DC converter.  
					J3  
					DB9 for Serial Port 1  
					JP11 and JP12  
					Leave JP11 and JP12 open for RS232 mode on serial port 1. Install  
					jumper on JP11 for RS422 (4-wire) mode. Install JP11 and JP12 for  
					RS485 (2 wire mode)  
					JP17  
					Serial Port 1 break-out header. Leave jumpers installed to route  
					module signals to J3 DB9 serial port  
					JP18  
					JP8 and JP9  
					Serial Port 2 RS232 header. Pin 1 TX(out), pin 2 GND, pin 3 RX(in)  
					Jumpers for serial port 2 selection, install positions 1 to 2 to route  
					serial port 2 to JP18 RS232 port. Install positions 2 to 3 to route  
					serial port 2 to J5 USB to serial converter port.  
					J6  
					J2  
					USB device port (xPico Wi-Fi only)  
					RJ45 Ethernet Socket. This is not used with the xPico Wi-Fi module,  
					it can be used if a xPico serial to Ethernet Device Server module is  
					used in place of the xPico Wi-Fi  
					JP14, JP15  
					Voltage test pins. Monitor only. JP14 is 3.3V and JP15 is Ground  
					Connecting an xPico Wi-Fi Device  
					Connecting Power to the xPico Wi-Fi Evaluation Module  
					There are five methods of providing power to the Evaluation Kit PCB. Use one of the  
					methods below.  
					1. Connect the provided universal power supply with mini-USB connector to J5.  
					2. Connect the USB to serial converter port J5 to a PC USB host port  
					3. Connect the USB device port J6 to a PC USB Host Port (xPico Wi-Fi only)  
					4. Connect a battery pack or external power supply (2.2V to 5.5V) between JP19 pin 1  
					(+) and JP19 pin 2 (-)  
					5. Connect Ethernet Port to a Power over Ethernet complaint PSE source (xPico  
					module only)
