Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note:
Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.

1. Overview
This document describes the AirPrime HL78xx Series Development Kit Rev4 (PCB board version:
5303247) and how it integrates with the AirPrime HL78xx series of embedded modules via a specific
snap-in connector. It also briefly describes the different interfaces and peripheral connections
supported by the Development Kit and provides schematics to facilitate the user’s understanding and
configuration of the Development Kit board for their own application use.
The Development Kit may be used to develop both software and hardware applications based on
embedded modules from the AirPrime HL78xx series.
The following table enumerates the different HL78xx variants that can be used with the Development
Kit.
Table 1.
Supported Module Variants
Variant Name
Description
HL7800
1.8V, LTE Cat-M1 and Cat-NB1, and capable with GLONASS support
HL7802
1.8V, LTE Cat-1 and Cat-NB1, GSM/GPRS class 10, E-GSM 900/DCS 1800, and capable
with GLONASS support
For more information about the AirPrime HL78xx series of embedded modules, refer to the product
technical specifications listed in section 6 Reference Documents.

This section gives a brief overview of the Development Kit and briefly describes the interfaces and
special jumper pads available; and lists all available test points on the Development Kit board.
2.1.
RoHS Compliance
The AirPrime HL78xx Series Development Kit Rev4 is compliant with RoHS (Restriction of Hazardous
Substances in Electrical and Electronic Equipment) Directive 2011/65/EU which sets limits for the use
of certain restricted hazardous substances. This directive states that “from 1st July 2006, new
electrical and electronic equipment put on the market does not contain lead, mercury, cadmium,
hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE)”.
The AirPrime HL78xx series of embedded modules are also compliant with this directive.

DC power jack connector via CN800
•
Connector via CN801
•
Connector via CN802
Figure 9.
VBATT_APPLI Connector (on the top side of the Development Kit)

VBATT_BB and VBATT_RF Connectors (on the bottom side of the Development Kit)
Three powers supplies can be used to supply the Development Kit and the HL78xx module. They can
be used to supply power to VBATT_APPLI, VBATT_BB and VBATT_RF separately or they can
provide supply collectively depending on CN803 and/or CN804 jumper configurations.
To measure the global current consumed by the HL78xx module (baseband + radio frequency),
disconnect CN803 and supply the Development Kit separately.
VBATT_BB and VBATT_RF of the embedded module can be measured separately or as a total
current drain depending on the configurations of CN803 and CN804.

POWER_ON_N
The Development Kit includes a POWER_ON_N switch, SW203, to start the HL78xx module.
Once the Development Kit is connected to an external source, the HL78xx module will start
monitoring the POWER_ON_N pin for a power on event.
The module may be enabled by switching SW203 to the “ON” position, and disabled by moving it to
the “OFF” position.
A green LED, D1106, indicates the POWER_ON_N state. When this LED is lit, it indicates that the
module is powered on.
The module can be powered off by disconnecting the Development Kit from the power source or by
issuing the appropriate AT command. For more information about AT commands, refer to document
[1] AirPrime HL78xx Series AT Commands Interface Guide.

The WAKE-UP pushbutton starts a wake when it is always activated.
The WAKE-UP pin is used to wake up the system from ultra-low power modes (from OFF mode,
Sleep mode, FAST_SHUTDOWN, or after a software power off). This signal should be set to high
level (external 1.8V) for at least a few milliseconds until the system is active to wake the module up
from these modes.

Audio
The headset jack available on the Development Kit, CN602, is a 4-pin RJ22 and allows the HL78xx
module to connect to an audio interface.
An audio codec, W681360YG from WINBOND, is mounted on the Development Kit and is used to
translate the embedded module’s digital audio interface or PCM interface into an analog audio signal.
This was done because performance and functionality tests are run under analog audio levels, and
because final customer applications are also in analog.
An audio amplifier chipset is mounted on the Development Kit ; the audio amplifier interface can be
disabled by switching SW600 to the “OFF” position and enabled by switching it to the “ON” position.
A green LED, D601, indicates the audio amplifier state. When this LED is lit, it indicates that the audio
amplifier is activated.
Jumper solder pads F600 and F601 are used to enable or disable the audio amplifier speaker signals
with headset jack RJ22, CN602. These two jumpers solder pads are soldered by default.
When the audio amplifier interface is switched ON, it is recommended to use audio jack, CN601, for
microphone and for amplified earphone.
