TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
This guide instructs the kernel driver integration development for Huawei modules based on Linux operating system (OS), such as Android, Ubuntu and Chrome OS. It is intended for the driver developers of the products based on Linux kernel OS.
This guide explains how to make a dial up connection with Linux.
This document describes how electrostatic discharge (ESD) occurs, how to conduct ESD tests, how interfering signals resulted from ESD are coupled to circuits of electronic devices, and what rules need to be followed during ESD design for Huawei LGA modules. Following these rules can provide users with good ESD performance during applications of Huawei LGA modules.
This document describes the rules and precautions of designing Printed Circuit Board (PCB) interconnection for the HUAWEI LGA module. By observing the rules, users can ensure the performance of this module in use and reduce costs effectively.
This guide instructs the kernel driver integration development for Huawei Modules based on Embedded Linux & Android operating system. It is intended for the driver developers of the products based on Embedded Linux & Android OS.
This document provides instructions for storage, packing, SMT assembly, and rework of the HUAWEI LGA module, and serves as a guide to secondary assembly of the HUAWEI LGA module. Meanwhile, this document provides PCB design guide for module assembly requirements of producibility and maintainability
The HUAWEI LGA module has two types of packaging:
PCB145-3030M: 145 pin LGA with a dimension of 30 mm × 30 mm
PCB114-3020M: 114 pin LGA with a dimension of 30 mm × 20 mm
The purpose of this document is to describe some hardware specification which is useful to develop a product with HUAWEI LGA module supporting PCM (Pulse- Coded Modulation). This document is intended for HUAWEI customers who are integrators and about to implement their applications by using our module.
The HUAWEI LGA module supports the PCM, which can be used for the module to transmit and receive digital audio data. Linear and μ-law codecs are supported. The HUAWEI LGA module uses the PCM interface as part of the audio front end; it easily allows for an external codec to be used instead of the internal codec. As an example, through the PCM you could connect a HUAWEI LGA module to a Bluetooth device.
The HUAWEI LGA module has one PCM port. Please refer to the Hardware Guide of the module that you are in use to know the PIN number of the PCM ports.
Communications through universal asynchronous receiver/transmitter (UART) serial ports is convenient and reliable. UART serial ports are widely adopted in Huawei modules. This design guide describes the serial port specifications of Huawei modules and provides recommended design schemes for peripheral circuits. When designing UART serial ports for Huawei modules, customers can refer to this document.
Most of Huawei modules provide 8-wire serial ports with flow control. These 8-wire serial ports can also be used as 2-wire or 4-wire serial ports.
This document is intended to provide references for customers to do module firmware update over the air. Customers need to refer to this document to develop the host application. This document also contains examples and relevant description. Huawei module and the related firmware in the table below support the FOTA service.
This document briefly describes the power management related connection hardware between the host and module.
This document does not describe the host system software. For example, if the host runs on a Windows or Mac system, Huawei will provide a USB driver program corresponding to the module. If the host runs on an Android system, Huawei will provide Guide to Kernel Driver Integration in Android System for Huawei WCDMA or CDMA Module for users to configure the USB-based wakeup function of the module.
This document describes typical application scenarios of the module. A host can be designed based on the actual system features and the application scenarios of the module to reduce power consumption of both the module and integrated product.
For details about the module's performance indicators, refer to relevant description in HUAWEI MU509 Series HSDPA LGA Module Hardware Guide.
