L710HG EVB User Manual 2 Abstract L710HG Evaluation Board (silkscreen L506_EVB ) Is specially designed for developing L710HG serial module，To help developers to develop, debug, test L710HG series 4 GIoT LTE module. Below and mark shows L710HG the main functions of the development board. In this article, we will in the subsequent chapters on the function of each part is described. Figure 2-1: L710HG EVB global graph The above picture description: 1. The L710HG USB port is on the EPI board, not on the EVB.
L710HG EVB User Manual 3 Power Supply L710HG development board provides two methods for power supply: External DC 5 V adapter and 3.8 V DC power supply directly. Through an external DC 5 V adapter power supply, the power supply voltage regulator on the development board piece of power supply will be converted to about 3.8 V, power supply for the module. These two modes can be switched by S1. Switch S1 to the top when using DC 5V adapter and Switch S1 to the bottom when using battery power.
L710HG EVB User Manual 4 Key Description L710HG development board with a total of 5 top pressure switch and 14 dial switch. 5 top pressure for short press trigger control, 14 dial switch (single pole double throw) for the long time state toggle switch. The corresponding function on the L710HG development board has a corresponding printing information, the function of the specific instructions are as follows: 4.1 Power on/off and RESET key When power supply for the EVB, the power indicator will light up.
L710HG EVB User Manual 4.3 WATCHDOG key Press the WDOG key and the PWRKEY key at the same time will disable the watchdog function. Normally on, the watchdog function is enabled, the system will feed the dog regularly. The watchdog button is mainly used for software debug.
L710HG EVB User Manual 5 Application interface 5.1 UART DB9 Interface There is a DB9 COM port on the L710HG development board, and its signal pin is consistent with the signal on the L710HG module. The serial interface as the main serial port can support complete 9 - line RS232. The COMS 1.8v level on the L710HG module is converted to the standard RS232 level via serial port level conversion chip SP3238.
L710HG EVB User Manual Figure5-2: USB（AT UART）Port 5.3 USB（DEBUG UART）Interface When software is debugging and analyzing problems, LOG can be captured by USB virtual DEBUG serial port. In use, you need to dial the switch S4 to the left. After the serial port is inserted into USB, DB9 serial port is closed. Sending AT can only use the USB virtual serial port mentioned in 5.2. Figure5-3: USB（DEBUG UART）Port 5.4 USB 2.0 Interface The L710HG module supports USB 2.
L710HG EVB User Manual Figure5-4: USB 2.0 Port 5.5 SIM Card Interface L710HG support one single voltage (1.8V) SIM interface, but for the convenience of users, we have provided two SIM holder interface. it’s standard SIM card slot and Micro SIM card slot.
L710HG EVB User Manual Figure5-6: Chinese standard earphone 5.7 Antenna interface The L710HG antenna interface is located on the module load board mounted on the EVB board and provides two antenna interfaces, one of which is the main antenna port, directly connected to the antenna for wireless function, and the other is the GPS antenna interface. Main antenna interface adopts SMA head, connected to the supporting external antenna by cable; GPS antenna USES IPX interface.
L710HG EVB User Manual automatically enables the power and crystal oscillator of CODEC. The switch S3 is the selection switch of CODEC. When switching S3 to the top, CODEC uses MAX9867ETJ+ chip. When using the MAX9867ETJ+ chip, the sound comes from the earphone, the Chinese standard earphone needs to be plugged in. Switch S3 to the bottom, the CODEC chip is NUA8814. At this time, the sound comes from the SPK end, and 8 ohm horn can be welded to the SPK end.
L710HG EVB User Manual sound chamber structure. Because in our EVB there is no sound chamber, so it only make sure the function is OK or not. 5.9 LED indicating lamp The development board has 13 functional indicators to indicate the status of different functional units.
