ModFLEX™ Shields for Arduino

LSR’s ModFLEX™ Shields for Arduino offer unparalleled wireless design capabilities for Arduino aficionados and design engineers exploring the ease of developing 802.15.4 wireless applications at either 900 MHz or 2.4 GHz. Simple repeating and source-routed proprietary networks using the popular modular platform are enabled with LSR’s FLEXConnect™ technology.

The SiFLEX02 Shield for Arduino (MPN 450-0060) is based on the popular and powerful 900 MHz 802.15.4/ZigBee® transceiver module, capable of transmission up to two miles outdoors. The FCC- and IC- certified SiFLEX02 module, while delivering high performance RF transmit power & receive sensitivity, consumes very little power – roughly 2 ?A in sleep mode, 30 mA in receive mode, and 285 mA when transmitting. Ideal for a variety of applications, the SiFLEX02 is industrial-temp certified to 85°C.

LSR’s ProFLEX01 Shield for Arduino (MPN 450-0058) is based on LSR’s FCC- and IC- certified 2.4 GHz 802.15.4/ZigBee® Pro transceiver module, the ProFLEX01. This module offers state-of-the-art selectivity/co-existence, excellent link budget, operation up to 85°C and low power consumption. In addition, the transceiver in the ProFLEX01 provides extensive hardware support for frame handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and frame timing information, all of which reduces the load on a host controller. Well suited for battery-powered applications, the ProFLEX01 module draws about 3 ?A in sleep mode, 30 mA in receive mode, and 145 mA in transmit.

Both the SiFLEX02 and ProFLEX01 modules are designed to be used as open hardware platforms as well, each developed using low power programmable microcontrollers and both having on-module Flash memory to support an end-user’s specific application code.

ModFLEX Development Board

LEDs
There are four LEDs on the Development board.

  • The green LED in the lower right corner of the board indicates power to the module.
  • Green: Heartbeat LED from micro
  • Red: RF activity
  • Yellow: Host serial activity

Jumper Headers
The three rows of jumper headers on the Development Board can be used to connect the module to the development board circuitry or outside world.

To connect the module pins to their development board periphery circuits the respective pins need to be jumpered together. To isolate the module remove the jumpers. The jumper pins can be used to connect the ModFLEX module to an application circuit and/or test/debug equipment, such as a multi-meter or oscilloscope.

In order to program or debug the ModFLEX module, the jumpers bridging module pins 9 through 14, and 26 will need to be in place.
Development board jumpers

Power Supply
The SiFLEX02-R2-HP requires an external 4.0V power supply connected to pins 6 and 7 of the module to power the PA. This power supply is not supplied in the development kit.

SiFLEX02-R2-HP Zigbee module power supply

USB or Battery Power
There are two basic ways of powering the Development Board via header J2. When the jumper is in the VREG position there are three inputs that can feed the on-board regulator: USB, bench power supply, or a plug-in AC adapter. When the jumper is in the VBAT position the board is fed directly from the AA batteries (does not go through the regulator).

Introduction

The Ping Pong Range Test allows a user to easily verify range between two transceivers via feedback of three flashing LEDs. Running the Ping Pong Range Test requires the use of two development boards. One board will be the master, and the other board will be the slave. The master periodically transmits packets to the slave. If the slave receives a packet, it will flash its LEDs and transmit a packet back to the master. If the master receives a packet from the slave, it will flash its LEDs.

In Ping Pong Range Test LEDs indicate signal strength (high, medium or low signal strength). If the LEDs do not light, the packet was not received.

Enabling Ping Pong Range Test

As Master

  1. Press the RESET button and the USER1 button simultaneously.
  2. Release the RESET button.
  3. Wait until green LED1 is lit, then release the USER1 button.

As Slave

  1. Press the RESET button and the USER2 button simultaneously.
  2. Release the RESET button.
  3. Wait until red LED3 is lit, then release the USER button.

Evaluating Range
During the Ping Pong Range Test the boards will flash their LEDs based on received packet signal strength. Further data to evaluate range can be obtained using the LSR ModFLEX Test Tool Suite. Refer to table below for a description of the LEDs versus signal strength.

LED Signal Strength
Green Excellent
Yellow Good
Red Marginal
Off None

Changing RF Channels

In case there is a lot of traffic on the default channel it is possible to change the channel.

  • For ProFLEX01 the default channel is 14 (2420 MHz).
  • For SiFLEX02-R2 the default channel is 5 (914 MHz).

The RF channel can be changed only after the test has been started.

While running the Ping Pong Range Test, the current channel can be changed to one of three unique channels. This is accomplished by holding the USER1 button for approximately two seconds, at which point the green LED1 will be lit steady. Once the push button is released, the current channel option number (one through three) is displayed by a series of flashes on the red LED3. Each short USER1 button press will increment the channel option number and display it with a given number of flashes on the red LED3. To accept the last selected channel, hold the USER1 button until the green LED1 goes out (approximately two seconds). After again releasing the button, the device will return to the Ping Pong Range Test.

Supporting Ping Pong Range Test on Host Board

The Ping Pong Range Test firmware is built into the module firmware. This allows for the test to be used on the application host board. The following considerations need to be made in order to utilize the test.

Power
A nominal 3.3 VDC power supply should be connected to the VCC - 3V3DC pin (26) on the module. Also, a ground connection on the GND pin (44) is required. Be sure the power supply is capable of supplying the module with enough power.

LED’s
Three LEDs should be connected to module pins 27-29. The cathode of each LED should be each pin. The anode of each LED should be connected to the 3.3 V power supply through a nominal resistor value in the range of 100 to 470 ohms depending on the LED and desired brightness. Module pin 27 should connect to a green LED, pin 28 should connect to a yellow LED, and pin 29 to a red LED.

Switches
Module pins 30 (USER2) and 31 (USER1) should be connected to a normally open tact switch with a 10k ohm pull-up resistor. These switches are referred to as the USER1 and USER2 buttons in the subsequent instructions.

Also, the RESET pin should be connected to a normally open tact switch with the other end of the tact switch grounded. This switch is referred to as the RESET button in the subsequent instructions.

F Antenna

Modules with a F Antenna have been tuned assuming free air dialectic. This means there can be no PCB material underneath the antenna for it to operate properly. A couple common options address this.

Overhang Module off Host PCB

The carrier board should be designed so the module overhangs the edge of the board 0.23” as pictured below.
ModFLEX antenna overhang

Host PCB Opening
Minimum host PCB opening for ModFLEX

U.FL Connectors

If using the U.FL connector with an external antenna, or the helical antenna, you do not need the extra provisions in the footprint for a wire or castellated antenna. Also you do not need to hang the module off the end of the carrier board or have a cut out in the carrier board. However if concerned with compatibility with other LSR ModFLEX modules this should be considered.
U.FL Footprint for ModFLEX

Wire Antenna
The wire antenna and solder protruding on the bottom side of the module needs to be seated in a hole so the module does not lift off the host board. See the footprint information in the datasheet for the location of this hole.

Helical Antenna

If using the U.FL connector with an external antenna, or the helical antenna, you do not need the extra provisions in the footprint for a wire or castellated antenna. Also you do not need to hang the module off the end of the carrier board or have a cut out in the carrier board. However, if concerned with compatibility with other LSR ModFLEX modules this should be considered.

RF Castellation
The castellated antenna option allows the use of a RF connector or PCB trace antenna on the modules carrier board. This option is NOT included with the Module’s FCC/IC Certification. It will require an additional certification. LS Research is equipped with a certification lab and can assist in getting this done at a reasonable cost in a short period of time.

The castellated antenna option is NOT available on all ModFLEX modules from LS Research. Use of the castellated antenna will require the three pads shown below. If the castellated antenna option is not needed the pads may be eliminated from the footprint.
RF castellation footprint

Special care in routing the RF signal on the carrier board is needed. LS Research has a full palette of design services, including RF board layout, and would be happy to assist. Other guidelines are listed below:

  • Keep the RF trace as short as possible.
  • Ensure the impedance of the RF trace is kept at 50 ohms.

RF connector, ground and RF Trace

Extraction of U.FL Connectors

Care should be taken when mating or un-mating the U.FL plug from its receptacle as they are designed (by the manufacturer Hirose) for a maximum of 30 cycles (in practice probably anything more than five cycles is too much). The outer shell of the mating plug can bend or deform easily and not make good electrical contact, thus degrading RF performance - sometimes significantly.
Mating or un-mating the U.FL plug from its receptacle more than five cycles is too much

A special tool exists to safely remove the u.fl cable. LSR recommends the Hirose Electronics tool, part number U.FL-LP(V)-N-2.
U.FL removal tool

Use the tool as shown below to remove the u.fl cable from the connector.
U.FL cable assembly

Hand Soldering

The ModFLEX modules have two 0.032” diameter non-plated holes in the PCB that can be used to align the module to the carrier board. When designing the carrier board it is recommended to include two matching alignment holes.
Alignment holes for ModFLEX modules

Wire Antenna Performance

The best antenna performance can be achieved by having the wire antenna perpendicular to the module as illustrated below.
