## **Description** 

The RN-131 module is a standalone, embedded wireless 802.11 b/g networking module. With its small form factor and extremely low power consumption, the RN-131 is perfect for mobile wireless applications such as asset monitoring, GPS tracking, and battery sensors. The WiFly module incorporates a 2.4-GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management, and analog sensor interfaces as shown in Figure 1. The module is preloaded with software to simplify integration and minimize application development. In the simplest configuration, the hardware requires only four connections (PWR, TX, RX, and GND) to create a wireless data connection. Additionally, the sensor interface provides temperature, audio, motion, acceleration, and other analog data without requiring additional hardware. The module is programmed and controlled with a simple ASCII command language. Once the module is set up, it can scan to find an access point, associate, authenticate, and connect over any Wi-Fi network.

## **DESIGN CONCERNS** 

The following sections provide information on designing with the RN-131 module, including radio interference, grounding, solder reflow, connection status, etc. 

## **Minimizing Radio Interference** 

When integrating the WiFly module with the on-board chip antenna, ensure that the area around the chip antenna end of the module protrudes at least 6 mm from the motherboard and any metal enclosure. If this placement is not possible, use the on-board U.FL connector to route to an external antenna. 

The 8.5-mm area under the module’s antenna end should be kept clear of metallic components, connectors, vias, traces, and other materials that can interfere with the radio signal. See Figure 6.

**RN-131-DS** 

## **Grounding Recommendations** 

For the module antenna to function, pins 36 through 44 must be connected to ground. Roving Networks suggests you place the module such that 0.5 mm of theses pads is exposed. This placement provides access for soldering pins 36 through 44 from below, and provides ample clearance of the antenna from the PCB. See Figure 7. 

**Figure 7. Module Placement for Grounding**

To reflow solder the module onto a PCB, Roving Networks<br>recommends an RoHS-compliant solder paste equivalent to NIHON ALMIT paste or OMNIX OM-310 solder paste from<br>Alpha metals. See Table 6.<br>**----- End of picture text -----**<br>


**NOTE:** Use no-clean flux and DO NOT water wash.

## **U.FL Connector** 

Roving Networks recommends that you use the Hirose U.FL connector (part number U.FL-R-SMT) for connecting external antennas. If you prefer to use the SMA connector, use the Roving Networks U.FL-to-SMA cable (part number RN-UFLSMA6). Figure 10 shows the U.FL connector dimensions.

**RN-131-DS** 

## **Connection Status** 

GPIO4, GPIO5, and GPIO6 drive status the LEDs. 

- GPIO4 indicates the TCP/IP connection status. This signal is on high for an active connection, toggles fast to indicate no IP address, and toggles slowly to indicate that the IP address is OK but not connected. 

- GPIO6 indicates the association status. High means the module is not associated with a network, off indicates that it is associated and Internet access is OK. 

- GPIO5 toggles when data is transferred. 

## **Keep-Out Areas** 

When designing your PCB avoid exposed traces and vias beneath the module. Figure 11 shows areas on the module that should be kept clear. 

**Figure 11. Keep Out Areas** 

**==> picture [335 x 69] intentionally omitted <==**

## **Powering the Module** 

The module can be powered from either 3.0-V DC batteries or 3.3-V DC regulated power. 

For 3.0-V DC battery power: 

   - Apply power to pin 20 (VDD-BATT). 

   - Short pin 17 (3.3 V REG-OUT) to pin 18 (3.3 V REG-IN) (battery boost mode). 

- 150 mA of current at 3.3 V is available for external devices on pin 21 when the module is in battery boost mode. 

- For 3.3-V DC power: 

   - Apply power to pin 20 (VDD-BATT) and pin 21 (VDD-IN). 

   - Connect pin 18 (3.3 V REG-IN) to ground and leave pin 17 (3.3 V REG-OUT) unconnected.

Version 3.2r 4/9/2012

**RN-131-DS** 

## **Reset (Pin 5)** 

The RESET signal is used to reset the module and is active low. This pin has a built-in 100-kΩ pull up resistor. You do not need to connect this; it can be left unconnected. To reset the module, apply a 3.3-V pulse for a minimum of 160 us. 

## **Force Awake (Pin 9)** 

This signal forces the module to wake up from sleep. FORCE_AWAKE is an active-high signal. To wake the module, apply a 3.3-V pulse for a minimum of 250 us. 

## **Achieving Lowest Power in Sleep Mode** 

To achieve the lowest power consumption (4 uA) in sleep mode, connect a weak pull-down (100 KΩ resistor to GND) on pin 22 (DMA-TX). 

If GPIO8 through GPIO4 are being used to drive an output, connect a 100-kΩ pull-down resistor. Any unused (no connect) GPIO pins can be left floating. 

- Pin 25: GPIO8 

- Pin 26: GPIO7 

- Pin 27: GPIO6 

- Pin 28: GPIO5 

- Pin 29: GPIO4 

For other GPIO lines, you do not need to use a pull down. The module already has an on-chip internal pull down (80 kΩ 

The power consumption in sleep mode without these signals connected to a pull down is 655 uA. 

## **Sensor Interfaces** 

Inputs must not exceed 1.2 V.  The sensitivity saturates at 400 mV. 

## **Ad Hoc Mode & Restoring Factory Settings** 

Ad hoc mode is controlled with GPIO9 (pin 24). Roving Networks recommends that you connect pin 24 to a switch or jumper connected to a pull up. When GPIO9 is driven high at power up, the module enters ad hoc mode. If GPIO9 is then toggled low 5 times, the module will be restored to it’s initial factory default configuration. This feature is useful for cases where the module is misconfigured and is no long responding.
