xPico 200 Series Evaluation Kit User Guide
This guide describes how to setup the xPico® 200 series evaluation kit and provides the
information needed to evaluate the included xPico 240 or xPico 250 embedded gateway
modules. The intended audience is the engineers that design the xPico 200 into their
products.
Evaluation Kit Contents
Lantronix® xPico® 200 series allows OEMs to go to market faster with their smart
connected products. It delivers seamless and secure Ethernet, Wi-Fi and/or Bluetooth®
connectivity. Featuring advanced enterprise security, complete Wi-Fi®, network and
Bluetooth stack offload, essential applications for data connectivity and control, pre-
integration with the MACH10™ platform, the xPico 200 series delivers embedded
gateway capability in an industry-leading compact footprint.

The evaluation kit is available in two different variants depending on xPico 200 series
model that is mounted:
1. XPC240300EK - xPico 240 module (Ethernet + Wi-Fi)
2. XPC250300EK - xPico 250 module (Ethernet + Wi-Fi + Bluetooth)
Evaluation Kit Contents:
xPico 200 module (xPico 240 or xPico 250 model) on an edge card
xPico 200 evaluation board with socket for xPico 200 edge card module
5V DC power supply adapter (with international plugs)
2x Antennas with u.fl to R-SMA adapter cable
EvaluationKitDescription
The xPico 200 evaluation kit provides a test platform for the Lantronix xPico 200
gateway module. The evaluation kit uses either 5V power from a USB device port
connector or power supplied 5V barrel connector. The evaluation kit includes all
necessary regulators to power the 3.3V xPico 200 module.
The evaluation kit has the following features:
One DB9M serial port connector with an RS232 transceiver at rates up to 1 Mbps
One RJ45 10/100 Ethernet port with on board PHY and magnetic module
One mini-type B USB device port connector for 5V input power and device port connection to
the xPico 200 module. This port can also be jumpered to act as a Host port for engineering
evaluation. Refer to the xPico 200 Series Embedded Wi-Fi Gateway Integration Guide and
USB.org for proper USB compliant host port implementation.
LEDs for the xPico Ethernet and system status outputs
Access to all logic level IO signals on the xPico 200 via header pins for measurements and
connections to other places
The xPico 240/250 Evaluation Board image shows the xPico 200 evaluation kit with an
attached xPico 200 module, highlighting all of the connectors and configuration
jumpers. The Connectors, Header and Switches table lists each of the connectors and
jumper headers along with their function. Further description and pin assignments are
included in subsequent sections.

SerialInterface
The evaluation kit has one RS232 port for connection to the xPico 200 internal UART.
Serial port 1 is a DB9M (DTE) connector labeled J6. The null modem cable can be used
to connect J6 directly to a standard PC RS232 serial port.

Note
The evaluation board is configured for RS232 on the UART signals. If attempting to use
the J2 UART TTL header pins instead of the RS232 transceiver, pin 22 of the serial
transceiver (U8) should be tied to ground.
EthernetInterface
The xPico 200 evaluation kit includes one RJ45 connector with on-board magnetics for
connection to the xPico 200 module 10/100Mbps Ethernet interface. Connector J3 is the
Ethernet port.

PowerSupply
The evaluation kit provides multiple input Power Options. Included with the kit is a 5V
wall adapter which plugs into barrel connector J4. In addition to powering from the wall
adapter, the evaluation kit can be powered from a standard PC USB Host port by
connecting a USB cable between the PC and J9. If powered via USB, the unit must be
configured for USB device mode (JP3 pins 1 to 2, JP5 out, JP6 out).
