GENERAL INFORMATION
The WiFi-IT wireless module is a low cost, easy to integrate, robust solution for providing
low to mid-speed WLAN communication. WiFi-IT is perfectly suited for creating sensorbased networks that require no additional programming. The module supports a wide range
of interfaces including, UART, SPI (master and slave), I2C, Digital, Analog and Pulse Width
Modulated (PWM). Multiple active interfaces are supported! WiFi-IT is compatible with
standard 802.11 b/g wireless access points.

HARDWARE DESCRIPTION
The WiFi-IT module operates in the 2.4 GHz ISM band and supports two standard 802.11
b/g data rates, 1 Mb/s and 2 Mb/s.
The module provides a variety of hardware interfaces that may be active at any time. There
are two UARTs, each providing an asynchronous communication interface supporting all
standard bit rates up to 921.6 kbps. Both UARTs support hardware flow control, if enabled.
Two SPI interfaces provide dual synchronous serial communication and operate in either
slave or master modes. SPI 0, when configured as a master device, provides up to four chip
selects. One I2C port is provided supporting bit rates of up to 392 kbps. Three Pulse-Width
Modulation (PWM) outputs are provided. The PWM outputs operate in two modes; as
independent function blocks providing an output signal with programmable frequency and
duty cycle, or as synchronized PWM function blocks with programmable phase delay
between each PWM output. Two ADC inputs provide 10-bit A-to-D conversions at up to 32
ksps. ADC 0 can be configured as a DAC providing 10-bit D-to-A conversions. When ADC 0
is used as a DAC, ADC 1 is disabled and should be left unconnected. Unused pins are
available as General Purpose I/O (GPIO), which may be programmed as Input (default),
Output or Bi-Directional.
Two Alarm inputs are provided to wake the WiFi-IT from the power conservation sleep
mode. The Alarm inputs have programmable polarity and are Schmidt-triggered logic. The
Ready output goes active when the module is ready to communicate.
FIRMWARE DESCRIPTION
The WiFi-IT module is available preloaded in two different configurations. The Wireless-Wire
(L1) configuration requires no programming, just use the configuration application to setup
your desired operation parameters.
The WiFi-IT Basic (L2) application provides a Basic language interpreter, enabling the
engineer to design, code and debug their own applications. Using the WiFi-IT! Module and
WiFi-IT Basic you can replace the microprocessor in many embedded designs!
WIFI-IT! WIRELESS-WIRE
The Wireless-Wire application supports configuration of a nodes interface ports and control
engine. It is also used to setup the wireless communication parameters either remotely or
through an RS232/USB port on a Personal Computer.
Interface ports can be enabled and configured with the desired operating parameters. The
node control engine can me setup to operate in three unique modes:
1. Sleeping sensor node with timer or interrupt auto-reporting.
2. Sleeping data node with timer or interrupt auto-reporting.
3. Always-on node with interrupt, timer or continuous connection.
Once configured the WiFi-IT node permanently stores the settings and will operate, using
those settings, until they are changed. The Wireless-Wire Configuration application can
update node operating parameters over the wireless network at anytime.

WL10-G - 3/19/2010
WiFi-IT!™
WL10-G
WLAN Module
The Wireless-Wire protocol supports UDP communication between the node and an Access
Point. Communication between a Microsoft Windows® PC and the WiFi-IT nodes is directly
supported through a supplied virtual COM port (vCOM) driver. Once the vCOM port is
created the connection to the embedded system containing the WiFi-IT node operates just
as a wired connection. Data can be transferred from the embedded system or sent to the
embedded system through the vCOM port.
When operating with legacy RS232 equipment, no modifications to the legacy
communication protocol need to be made, in many instances. The Wireless-Wire wraps the
legacy communication messages in its own protocol for transmission and removes the
wrapper before forwarding the communication on to the legacy system.

Control Software
& vCOM
Wireless-Wire Configuration
Figure 1: L1 System
When operating in one of the sleep modes there may be a latency period until the node
leaves the sleeping state and connects to the WLAN. The vCOM port can be configured to
buffer messages until the node is available.
WIFI-IT BASIC (L2) APPLICATION
The WiFi-IT Basic application provides a higher level of control requiring programming to
implement a solution. Using the WiFi-IT development environment with WiFi-IT Basic,
sophisticated programs can be written providing direct program control of an embedded
system. WiFi-IT Basic provides a simplified Application Programming Interface (API) to the
WLAN, special sleep modes and control of the hardware interfaces. The WiFi-IT development
environment provides tools to debug the application and download it to a module. Once the
application has been verified the code can be burned into as many WiFi-IT L2 modules as
desired.
A WiFi-IT L2 module may replace the microprocessor in many embedded systems, providing
a cost effective wireless solution for the embedded system designer.

NOTES
1. If GPIO_27 is pulled high during boot, the module will enter program update mode
and wait for FLASH download via SSPI or UART 0.
2. GPIO_28 and GPIO_29 are sampled at reset to establish the JTAG configuration for
debugging. These signals should only be used as outputs and not be driven by an
external device.
3. Configured as input with pull-up active.
4. JTAG TDI is not equipped with a pull-up or pull-down resistor. It should not be left
floating.
5. Referenced to VDD_ADC.
6. Referenced to VDD.
GENERAL NOTES
All I/O signals are configured as inputs with pull-down active after power-up or reset.
Unless otherwise noted all signals are referenced to VDD_IO.

WIFI-IT MODULE PLACEMENT
The WiFi-IT module is available in two antenna configurations; internal chip antenna (WL10GC) and SMA antenna (WL10-GS) configuration. When using the WL10-GC care must be
taken to minimize signal loss. The chip antenna should be clear of any metallic components,
copper traces, internal layers and any ground or voltage planes. There should be at least a
5 mm clearance in all directions.
The WL10-GC module should not be enclosed in a metal enclosure.
FCC LABELING INSTRUCTIONS
When installing the WiFi-IT! module into equipment, the module FCC ID number must be
visible. If it is not visible then labeling that is clearly visible must be attached to the product
stating;
WL10-GS
“Contains FCC ID: XRH-1997”
WL10-GC
“Contains FCC ID: XRH-1997”
WIFI-IT MODULE CERTIFICATION
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications to this equipment. Such modifications could void the user’s authority to operate the
equipment.
The WiFi-IT! module has been certified by the FCC as a module that may be used in OEM equipment
without requiring re-certification as an FCC Class C device. To maintain this certification the WiFi-IT!
module must use only one of the two following antennas.

WIFI-IT! EDK - EVALUATION AND DEBUG DEVELOPMENT SYSTEM
The EDK evaluation and debug development system allows you to evaluate and develop
Wireless-Wire and WiFi-IT Basic applications using the WiFi-IT! module. Using a Microsoft
Windows® based application; you can configure WiFi-IT! modules, running Wireless-Wire
(L1) firmware and write and debug your own application code on modules running WiFi-IT
Basic (L2).
The EDK platform provides power, easy access to all of the WiFi-IT! interfaces and visual
indication of interface signaling, thereby reducing the need for an oscilloscope and/or logic
analyzer. In addition, the EDK supports access to the WiFi-IT!’s UART0 through the onboard
RS232 interface for setting configuration information, loading code and debugging
programs.
To evaluate the WiFi-IT! modules, NPE provides a configuration and administration program
which runs on Microsoft Windows based PCs and operates through a wired or wireless
connection. Configuration information is stored directly on the WiFi-IT! module, once
configured the node boots to that configuration when powered up.
