ABOUT iENBL Devkit
iENBL is a multi-sensor IoT development platform embedded in a ruggedized
clamshell enclosure with focus in LPWAN (Low Power Wide Area Network)
technologies. iENBL supports an easy to use software packages, enables developers to
develop and prototype IoT applications very quickly and smoothly
The highly integrated iENBL combines a high-performance ARM Cortex M4
microcontroller with 512 MB of memory, the sensors required for most IoT applications,
the short-range communication WiFi and BLE solutions, a few actuators and the
aforementioned LPWAN technologies.
iENBL-111B supports on unlicensed LPWAN solutions LoRa and Sigfox technologies

Should the IoT application need a sensor that is not included in the device, the iENBL is
expandable, and required sensors can connect to and be powered by the expansion port
(Figure 1). The expansion port is also used to program the device using a JTAG
programming interface.
The iENBL’s USB port is able to download new firmware and also charge the included
1.320 mAh rechargeable battery.

The iENBL also includes a microphone and an SD card slot for logging noise data in
predictive maintenance applications. Any of the sensors can be utilized to record data.
iENBL features a GNSS receiver which, when combined with the accelerometer, the
pressure sensor, the WiFi and BLE interfaces, and the geolocation capabilities of
LPWAN technologies, makes the iENBL an excellent platform to develop and test use
cases such as asset tracking for IoT applications. The GNSS receiver offers accurate
position information outdoors, while the LPWAN conveys rough position information in
both outdoor and indoor environments. The WiFi interface can leverage more precise
WiFi location databases, like those from Google or HERE, for indoor location
information. The BLE unit also provides an indoor location/position if a BLE beacon
infrastructure is available. The accelerometer can be employed as an energy-saving
device, updating the position information only when movement is detected. Finally, the
pressure sensor furnishes altitude information as well.

HOW TO USE YOUR iENBL DevKit?
Follow these instructions to start using the devkit
1. Charge the iENBL.
Charge the iENBL using a power adapter with micro-USB connection.
To charge the iENBL completely will take approximately 3 hours.
IMPORTANT: The power adapter should be specified to supply between 4.75V –
5.25V and 500mA –2100 mA
2. First start-up
The iENBL device is delivered in a dedicated shipping mode, to exit this mode
and start the device press and hold both buttons on the front of the device for
>10 seconds.
This will make the device start up for the first time and prepare it for
provisioning.
3. Steps for provisioning
Log on to your LoRa network providers website and follow their instructions to
enroll a new device using the DevEUI found on the iENBL device label.
After enrolling the device, use the generated AppEUI/JoinEUI and AppKey to
provision your iENBL device.

FAQs AND TROUBLESHOOTING
Q: What’s the operating temperature?
A: 5C to +35C
Q: Is iENBL water resistant or water proof?
A: No. iENBL includes a ruggedized clamshell casing
Q: How long does it take to fully charge iENBL?
A: Approximately 3 hours. For safety reasons charging will be automatically terminated
after approximately 6 hours even if the battery is not fully charged at that time.
Q: Is the battery removeable?
A: No, please do not use sharp objects to remove the battery.
Q: How can I use a sensor that is not included in iENBL?
A: Additional sensor can be used with the iENBL by connecting them to the external
expansion interface. The simplest way to do this is by using a sensor expansion board
that can be acquired though your Flex contact person.
Q: What’s the operating temperature?
A: 5C to +35C
Q: What are the supported development environments for iENBL?

PRODUCT SAFETY, TIPS, AND PRECAUTIONS
How to take care of iENBL.
Handle the iENBL, charger and accessories with care.
The following suggestions will help you keep iENBL operational.
Keep the iENBL dry. Precipitation, humidity, and all types of liquids or moisture can
contain minerals that corrode electronic circuits. If iENBL gets wet, let it dry.
WARNING: Failure to follow these safety instructions could result in fire, electric shock,
injury, or damage to phone or other property. Read all the safety information below
before using iENBL.
Battery charging tips and precautions
Charge the battery before using it for the first time or when it has been unused for
extended periods.
If the battery is completely discharged, the device cannot be turned on immediately
after the charger is connected. Allow the depleted battery to charge for several minutes
before turning on the device.
Using a power source other than a USB power adaptor, such as a computer, may result
in a longer charging time or not charging at all due to a lower electric current.
While charging, the device and the charger may heat up. This is normal and should not
affect the device’s lifespan or performance. If the battery gets hotter than usual, the
charger may stop charging.
Battery
Don’t attempt to replace the iENBL battery yourself—you may damage the battery,
which could cause overheating and injury.
Using damaged cables or wall adapters, or charging when moisture is present, can
cause fire, electric shock, injury, or damage to the phone or other property. Make sure
the USB cable is fully inserted into the power adapter before plugging the adapter into
a power outlet.
Storage
Do not use or store the iENBL in dusty or dirty areas as it will affect its performance.

iENBL-111B
OWNER’S MANUAL PN IENBL-111B DRAFT

OWNER’S MANUAL
Do not store the device in high temperatures, such as a parked car in the sun, or in cold
temperatures.
Operating temperature
It is recommended to use iENBL at temperatures from 5C to +35C.
Do not store your iENBL in very hot or very cold areas.
Handling
Do not drop, knock, or shake the iENBL. Rough handling can break it.
During extended operation, the device may feel warm. In most cases, this is normal.
Using connectors, ports, and switches
Never force a connector into a port or apply excessive pressure to a switch, because this
may cause damage. If the connector and port don’t join with reasonable ease, they
probably don’t match. Check for obstructions and make sure that the connector
matches the port and that you have positioned the connector correctly with respect to
the port.
Repairs and unauthorized modifications
Do not open the iENBL to reveal the components.
Do not open the iENBL to replace the batteries.
Unauthorized modifications may damage the device and violate regulations governing
radio devices.
Recycle
Always return your used electronic products, batteries, and packaging materials to
dedicated collection points. This way you help prevent uncontrolled waste disposal and
promote the recycling of materials. All materials of the device can be recovered as
materials and energy. Check how to recycle your products at www.call2recycle.org.
