Chapter 1:About the Module T he Digi Connect Wi-Wave module is an 802.11b/g WLAN communications module for use in embedded applications. The module is a single circuit card packaged in a PCI Express Mini Card form factor, and supports all the RF, analog, and digital circuitry necessary to implement WLAN functionality.
What’s on the module? What’s on the module? .................................................................................. Digi Connect WiWave 802.11 b/g module edge connector 8 The Digi Connect Wi-Wave 802.11 b/g module edge connector is a 52-pin connector whose pinout follows the standard PCI Express Mini Card edge connector pinout as stated in the PCI Express Mini Card Electromechanical Specification, Revision 1.
Digi Connect WiWave 802.11 b/g module edge connector: Pinout The module edge connector is configured as shown (signal direction w.r.t Wi-Wave): Pin Type WLAN Mini Card signal Pin Type WLAN Mini Card signal 1 n/a No connect 2 In Vcc_3.
USB peripheral controller USB peripheral controller .................................................................................. The module uses a peripheral USB controller to interface to either a full speed or high speed USB 2.0 link. The link first tries to communicate to the host system board at the high speed USB rate (480 Mbps). If not successful, the link reverts to the full speed USB rate (12 Mbps). This link is used for all communication between the module and the host system board.
..... Voltage regulators Voltage regulators .................................................................................. The module takes in 3.3V±9% (3.00V to 3.60V) as its main input power. This power is filtered and used as a 3.3V supply to portions of the digital logic. This power also acts as input to dedicated on-board voltage regulators.

What’s on the development board .................................................................................. Features Digi Connect Wi-Wave 802.
ABOUT THE DEVELOPMENT BOARD What’s on the development board The development board Unpopulated components 14 There are components on the development board that are currently not populated. These components allow the development board to be used in other applications. Digi Connect Wi-Wave 802.11 b/g Hardware Reference, Rev.
..... ABOUT THE DEVELOPMENT BOARD Digi Connect Wi-Wave802.11 b/g module connector, J52 Digi Connect Wi-Wave802.11 b/g module connector, J52 .................................................................................. Place the Digi Connect Wi-Wave 802.11 b/g module into the connector and support bracket, J52, on the development board.

ABOUT THE DEVELOPMENT BOARD Digi Connect Wi-Wave802.11 b/g module connector, J52 Note: 16 Signal direction w.r.t PCIe Mini Card. Pin Type Signal Pin Type Signal 1 n/a No connect 2 In Vcc_3.
LEDs ..... ABOUT THE DEVELOPMENT BOARD LEDs .................................................................................. LEDs: DS3-DS7 LED DS1 The switching regulator is adjusted to output +3.3VDC ± 5% or better. LED DS1 lights up when the regulator outputs +3.3V power. See “Power supply” on page 19 for more information. LED DS2 LED DS2 lights up when the host system supplies power over the USB bus.
ABOUT THE DEVELOPMENT BOARD Switches and reset functionality Switches and reset functionality .................................................................................. Voltage monitor The development board provides a power supply voltage monitor and reset generator. When the +3.3V regulated supply voltage drops below 2.93V, the reset signal — RESET# — is asserted for a minimum of 140 msec. This signal is connected to the Digi Connect Wi-Wave 802.
Power supply ..... ABOUT THE DEVELOPMENT BOARD Power supply .................................................................................. The development board provides a 3.3VDC switching power supply. Either a bench power supply or an AC wall adapter supplies input power to the development board. The required input voltage range is 9–30VDC. Input power jack, J3 The input power jack, J3, is a barrel connector that accepts 9-30 VDC. The power jack is labeled J3 on the development board.
ABOUT THE DEVELOPMENT BOARD USB peripheral interface, J4 USB peripheral interface, J4 .................................................................................. USB peripheral jack, J4 20 The USB Type B connector, J4, is the primary communications interface to the development board. The USB bus is routed from the USB peripheral jack to the appropriate module connector pins. Digi Connect Wi-Wave 802.11 b/g Hardware Reference, Rev.
Debug breakout header, P21 ..... ABOUT THE DEVELOPMENT BOARD Debug breakout header, P21 .................................................................................. The debug breakout header’s primary purpose is to provide access to the W_DISABLE# signal. The W_DISABLE# signal is typically used as a hardware means to disable RF transmissions from the module without software intervention. Debug breakout header signal map www.digiembedded.
ABOUT THE DEVELOPMENT BOARD Debug breakout header, P21 W_DISABLE# signal The active low W_DISABLE# signal is on pin 20 of the debug breakout header. GND signals are positioned adjacent to the W_DISABLE# signal on pins 18 and 19. To assert the W_DISABLE# signal to the module, place a jumper between either pins 18 and 20 or pins 19 and 20. As an alternative, you can drive this pin with a low voltage TTL or CMOS driver. When asserted, W_DISABLE# lights the DISABLE LED, DS3. 22 Digi Connect Wi-Wave 802.
U.FL and RP-SMA connectors ..... ABOUT THE DEVELOPMENT BOARD U.FL and RP-SMA connectors .................................................................................. U.FL connectors The development board has two U.FL connectors that pair with two RP-SMA connectors. U.FL connector X5pairs with RP-SMA connector J1;U.FL connector X4 pairs with RP-SMA connector J2. U.FL cables The development kit includes two U.FL-to-U.FL cables that can be used to connect the module and development board.
ABOUT THE DEVELOPMENT BOARD U.FL and RP-SMA connectors RP-SMA connectors RP-SMA Wi-Fi antennas are attached to the two RP-SMA connectors, J1 and J2. Single antenna configuration: Attach an RP-SMA antenna to RP-SMA connector J1. Dual antenna configuration: Attach RP-SMA antennas to both RP-SMA connectors J1 and J2. For more information 24 For information about the antenna(s), see Chapter 3, “Using the Antenna.” Digi Connect Wi-Wave 802.11 b/g Hardware Reference, Rev.
