The interface layout is as follows: 2 MEIG EVB Hardware resource feature list Product Features LCD Front CAM Back CAM Standard interface resources Description 30pin ZIF, 4 Lane MIPI-ZIF Signal interface, PWM regulator backlight, Capacitive touch screen 30pin B2B, 4 Lane MIPI-B2B Signal interface 24pin B2B, 4 Lane MIPI-B2B Signal interface, autofocus Two DB9 RS232 serial port 3.5mm stereo audio output interface Two-way microphone input board (1 main MIC, all the way noise reduction MIC), One way speaker output in the board One Road vibration motor Two groups of SIM card interface, hot swappable One T-card socket, hot swappable One way micro USB interface Three USB2.0 interface 5V DC voltage input On-board ready Five keys(Poweron、Vol+、Vol-、 Homekey、Reset) to use Gravity sensor Ambient light and proximity sensor resources Compass chip One 25pin ZIF,Used for external expansion of two-dimensional Expansion code scanning head interface A group of 1.8V expansion interface resources for external resources expansion of fingerprints or thermal printer and other functions (including SPI, I2C) PCB size Layers: 4 specifications Size:220mm*180mm*1.5mm 3 MEIG EVB Interface Description 3.1 LCD Interface MEIG EVB provides a LCD interface, a group of 30pin ZIF connector, ZIF connector with a 5-inch LCD, QHD resolution. The LCD with the TP for the capacitive TP, Driver IC on the touch screen FPC, EVB interface is for the I2C communication interface. 3.2 Power Interface 5V DC power supply, power line as shown below: 3.3 USB_BOOT Test Point There are USB_BOOT and VREG_L6_1P8 two test points in the SLM757 core board foot and EVB middle position, VREG_L6_1P8 is 1.8V voltage output; USB_BOOT is pulled up to 1.8V will force the system into download mode. These two test points are shorted for die download and emergency download mode. 3.4 SIM Card MEIG EVB supports two groups of SIM cards, both hot-swappable, dual-SIM dual standby. You can use the SIM card for calls, text messages, Internet access and other operations, , as shown below: 3.5 Antenna interface MEIG EVB has a total of 4 antenna interfaces, and compatible with the coaxial interface, Connected to the antenna, you can carry out the relevant functional operation, such as dial number, as shown below: 3.6 Keys MEIG EVB has 5 keys, you can choose the button to carry out the corresponding function operation. 3.7 USB Interface MEIG EVB USB has two external interfaces, the first for the micro USB external interface, support for USB debugging, OTG functions, U disk and other functions; the second is USB HUB for three sets of standard USB ports. The above two modes can be switched by DIP switch selection. Headset Interface Headset jack supports a 3.5mm headphone jack. 3.8 3.9 T 卡 T Card The push-push T card connector used in the MEIG EVB supports hot plugging. 3.10 Camera MEIG EVB supports two cameras. The back camera uses 24pin B2B interface connector to connect. Front connection using 30pin B2B interface connector. Pixel respectively is 8M pixels and front 5M pixels. 4 Attentions 1.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in any portable device. FCC Radiation Exposure Statement This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user body. If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: 2APJ4-SLM757 Or Contains FCC ID: 2APJ4-SLM757” When the module is installed inside another device, the user manual of the host must contain below warning statements; 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product. Any company of the host device which install this modular with Single modular approval should perform the test of radiated emissionand spurious emission according to FCC part 15C : 15.247 requirement,Only if the test result comply with FCC part 15C : 15.247 requirement,then the host can be sold legally. IC statement This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device. Cet appareil est conforme aux CNR exemptes de licence d'Industrie Canada . Son fonctionnement est soumis aux deux conditions suivantes : ( 1 ) Ce dispositif ne peut causer d'interférences ; etc ( 2 ) Ce dispositif doit accepter toute interférence , y compris les interférences qui peuvent causer un mauvais fonctionnement de l'appareil. A separation distance of at least 20 cm is maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons. Une distance de séparation d'au moins 20 cm est maintenue entre l'émetteur rayonnant structure (s) et le corps de l'utilisateur ou des personnes à proximité. For a host manufacture's using a certified modular, if (1) the module's IC number is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the IC number of the module is visible; then an additional permanent label referring to the enclosed module: "Contains Transmitter Module IC: " 23860-SLM757" or "Contains IC: 23860-SLM757" must be used.
