Because of its small form factor and extremely low power consumption, the RN-111B is perfect for mobile wireless applications such as asset monitoring, GPS tracking and portable devices. The Wifly modules include an on board TCP/IP stack and networking application programs such as telnet and ftp. The hardware requires only four connections (PWR, TX, RX, GND) to create a simple wireless data connection. The WiFly module is programmed via a straight forward ASCI command. Once is setup it can automatically associated and authenticate with a network, connect to remote hosts, and reliably transmit data, making your application accessible worldwide.

Can power from single battery cell. 801.11b compliant radio. CHIP ANT, U.FL, SMA options. UART Serial Port TTL level, speeds: 1200bps up to 921Kbps, even,odd parity. SPI port available. Low power consumption ( 1.0 Vdc. 2. Powering the WiFly Module. There are 3 options to power the RN-111b. • Supply 3.6 to 16VDC power to VIN (pin 13). Tie VREG (pin 14) to VBATT(pin 15). • Apply 3.3VDC regulated power to VDD (pin 17). • Apply battery = 2.0 to 3.0VDc to VBATT (pin 15). If VIN is powered, VREG will supply 3.3VDC output and can be used for other circuits, with a current limitation of 50 ma. Warning: Placing 5VDC or any voltage above 3.3Vdc into the VDD pins of the module will permanently damage the radio module. Be sure to use the VIN = pin 13 power pin for any power supplied that is > 3.3VDC. 3. Factory reset PIO9 (pin 8). It is a good idea to connect this pin to a switch, or jumper, or resistor, so it can be accessed. This pin can be used to reset the module to FACTORY DEFAULTS and is often critical in situations where the module has been mis-configured. 4. GPIO connections: Placing 3.3Vdc into the PIO’s while they are set as outputs will permanently damage the radio modules. The failure mode is a short across GND and VCC. Use a 10KΩ resistor in series or a 10KΩ pull up resistor for input and output PIO’s respectively. 5. Sensor connections. The Sensor inputs SENS1-8 are extremely sensitive to over voltage. Under no conditions should these pins be pulled high above 1.2VDC. Placing any voltage above this will permanently damage the radio module. 6. Connection status. PIO5 is available to drive an LED, and blinks at various speeds to indicate status. PIO2 is an output which directly reflects the connection state, it goes HIGH when connected, and LOW otherwise. 7. Using SPI bus for flash upgrade. While not required, this bus is very useful for configuring advanced parameters of the WiFly module. A 6pin header which can be implemented to gain access to this bus. A minimum-mode version could just use the SPI signals (4pins) and pickup ground and VCC from elsewhere on the design. 8. Minimizing Radio interference. When integrating the WiFly module with on board chip antenna be sure the area around the chip antenna end the module protrudes at least 5mm from the PCB and any metal enclosure. If this is not possible use the RN-111B-E (SMA jack) or RN-111B-R (Reverse polarity jack). 9. Connecting to the GPIO. Placing 3.3Vdc into the PIO’s while they are set as outputs will permanently damage the radio. The failure mode is short across GND and VCC. Use a 10KO resistor is series or a 10KO pull up resistor for input and output PIO’s respectively. • Make sure to connect a common ground when using the external TX, RX inputs on the 0 – 3.3Vdc • For a 3 wire DB-9 interface (tx, rx, gnd only) connect/short CTS to RTS, Factory default is hardware flow control enabled CTS and RTS connected. 809 University Avenue • Los Gatos, CA 95032 • Tel (408) 395-6539 • info@RovingNetworks.com RN-111B www.rovingnetworks.com DS-RN111B_V1 4/20/2009 • When using a 5.0Vdc Input, PIO’s require a 10K ohm series resistor. PIO’s are 0-3.3Vdc not 5 volt tolerant.
