Figure 4-1： Power on/off reset key 4.2 FORCED USB download key The L710 enables modules to enter forced download mode by pressing the FORCED USB BOOT button, at which point the FORCED USB BOOT will be pulled up to 1.8v. Before the system is powered on, press the FORCED USB BOOT key and the PWRKEY key at the same time to enable the L710 module to enter the forced download mode. Figure 4-2： forced usb download key 4.
L710 EVB User Manual Figure 4-3： WDOG key 5 Application interface 5.1 UART DB9 Interface There is a DB9 COM port on the L710 development board, and its signal pin is consistent with the signal on the L710 module. The serial interface as the main serial port can support complete 9 line RS232. The COMS 1.8v level on the L710 module is converted to the standard RS232 level via serial port level conversion chip SP3238.
L710 EVB User Manual Figure5-1: L710 RS232 (DB9) Port Note: .About the serial port baud rate associated Settings, please refer to L710 software user manual. 5.2 USB（AT UART）Interface In addition to the DB9 serial port described in 5.1 for AT communication, L506_EVB_V3 also provides a set of USB virtual serial ports with exactly the same functions as DB9 serial ports for AT instruction and data transmission. In use, also need to wave switch S4 to the right.
L710 EVB User Manual Figure5-3: USB（DEBUG UART）Port 5.4 USB 2.0 Interface The L710 module supports USB 2.0 with a maximum USB transfer rate of 480Mbps.Software version download can be download through this USB serial port. Figure5-4: USB 2.0 Port 5.5 SIMCard Interface L710 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.
L710 EVB User Manual Figure5-5: Standard SIM and Micro SIM Note：Because L710 only support one SIM card port, so can’t assemble two SIM card at the same time in your applications. 5.6 Headset Interface If the audio codec chip MAX9867ETJ+ is used in L506_EVB_V3, the MIC input and sound output are through headphone channels. Earphones need to use Chinese standard earphones. Figure5-6: Chinese standard earphone 5.
L710 EVB User Manual Figure5-7: Function module load plate and antenna interface Note: L710 has only one main antenna interface, and the user can only use ANT_MAIN as the antenna interface when it is actually used. 5.8 Audio interface（TBD） The L710 module supports 1-channel PCM channel, which can also be reused as I2S signal. When using, switch S2 and S3 are needed to cooperate. The switch S2 is a software and hardware switch.
L710 EVB User Manual is also developed based on NAU8814. The general block diagram is as follows: Note: Audio system is a very complicate system, it contains many factors, such as the 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.
