xPico 110 Module PCB Pads
76-pin castellation pads.
Note:
The evaluation kit comes with an xPico 110 already soldered onto the board, and is
ready for testing.
WARNING:
If you need to replace or install a new xPico 110 sample onto the evaluation
kit, an experienced SMT device soldering technician is highly recommended since the
xPico 110 requires all the solder pads to be connected, especially those Ground pads pin
71 to pin 76 underneath the module. These pads need to have no soldering voids as
possible to assure low impedance connections to Ground for best performance in both
functionality, and EMC tests.
J2
RJ45 Connector
10/100Mbps Ethernet connector. PoE powered device port. Functional for xPico Ethernet
modules.
J3
Serial Port 1 DB9M
Standard RS232/RS422/RS485 DB9M serial port connector.
J5
Mini USB-B Receptacle Connector
Standard USB device port that can be used to power the evaluation kit and/or drive the
evaluation kit USB-to-Serial converter. The USB serial port converter then can be
connected to the module second serial port via a jumper setting at JP8 and JP9
JP1
Module Power Jumper
Allows for voltage measurement of the xPico module current sense resistor. The current
sense resistor is 0.301 ohms. Thus, measured current in mA = measured voltage on JP1 *
1000 / 0.301 ohms
JP3
Default Button Jumper
Allows access to module reset to default signal and SW1 push button. Install jumper to use
SW1 as reset to default button.
JP4
Hardware Reset Button Jumper
Allows access to module Hardware reset signal and SW2 push button. Install jumper to
use SW2 as Hardware reset button.
JP5
Configurable Pin Header – 1
st
8 CPs
Provides access to xPico 110 module configurable pins CP1 to CP8
JP6
Ethernet ACT LED Header
Allows access to Ethernet activity LED4. Install jumper to use the LED on board.
JP7
Spare LED Header
Provides two additional LEDs. Jumper to desired active low signal to light LED6 and LED7
JP8
Serial Port 2 TX Source Header
Install jumper to select between DB9 serial port or USB-to-serial.
JP9
Serial Port 2 RX Source Header
Install jumper to select between DB9 serial port or USB-to-serial.
JP10
Ethernet LINK LED Header
Allows access to Ethernet LINK LED2. Install jumper to use the LED on board
JP11
Serial Port 1 RS232/RS422/RS485 Mode Jumper
Leave open for RS232 mode. Install for RS422/RS485
