TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
This document mainly describes the power supply design for Huawei modules. This document also provides Huawei modules' requirements for power supplies, which can be used as reference for designing power supplies for Huawei modules. This document is composed of four chapters:
Power Supply Requirements
Power Supply Design Requirements
External Power Supply Circuits
Recommendations for the Layout and Routing of External Power Supply Circuits
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 chapter provides a brief description of the M.2 module development kit (DVK), including:
- Introduction to the DVK
- Components of the DVK
The DVK provides a complete solution based on the data functions of the module.
For designers who adopt the module in their designs, the DVK facilitates their module-based programming and troubleshooting at the project development stage.
Consisting of a dedicated interface board and accessories, the DVK provides the following interfaces:
- One 5 V power supply input interface
- Two USB interfaces (one Micro USB port and one A-type USB port)
- One standard RS-232 interface: COM1 with 4-line
- Standard Subscriber Identity Module (SIM) card interface
- Two antenna connectors
The M.2 module is fixed to the DVK through the M.2 connector. The signals output from the module are transferred to the DVK for secondary development.
