AirPrime HL78xx Development Kit User Guide 41112256 3.0 December 04, 2018 Development Kit User Guide 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.

Interfaces 3.1. Power 3.1.1. Power Supply Three power supply sources are available on the Development Kit : • 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) Figure 10. 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. 41112256 Rev 3.0 December 04, 2018 27 Development Kit User Guide Interfaces Refer to the following figure for possible configuration settings: Configurations: Jack VBATT_APLLI CN800 Apply powers supplies normal use:only one power supply connected powers suplies dev-kit and module isolate connected connected connected all powers supplies isolate connected connected Connect VBATT_APPLI and VBATT_BB and VBATT_RF Figure 11.

Interfaces 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. Figure 20. POWER_ON_N Pushbutton Note: The HL78xx module will start regardless of whether switch SW203 is in the “ON” or “OFF” position. Table 10.

Interfaces WAKE-UP The Development Kit includes a WAKE-UP switch to wake the HL78xx module up. 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. Figure 22. WAKE-UP Pushbutton The state of WAKE-UP is indicated by a green LED and can be controlled by a test point. Table 12.

Interfaces RESET_IN_N The Development Kit includes a RESET_IN_N pushbutton to reset the HL78xx module. The RESET_IN_N pushbutton starts a general reset when it is pushed. Reset can only be executed after the module has been switched ON. Note: An operating system reset is preferred to a hardware reset. Figure 23.

Interfaces USB (Main) The main USB connection on the Development Kit is available from CN401 and can be used to communicate with the HL78xx module directly via a PC. CN401 is a receptacle USB Micro-AB connector. Figure 24. Micro-AB USB Connector Figure 25. Main USB Interface Table 14.

Interfaces 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. Figure 26.
