1 Overview

GM650 is an open platform that supports GSM/GPRS+GPS wireless industry module,

reserved CPU resources and a wealth of hardware interface which is widely used in

various industrial and commercial fields to provide high quality voice, message, data

business, GPS Location and other functions.

GM650 provide two kinds of GPS data interface mode: single-port and dual-port. If the

user’s MCU has only one UART interface, while need to support both GPRS

communications and GPS positioning function, that GM650 single-port mode provides the

perfect solution.

5 Pin Definition & Encapsulation

5.1 Pin Definition

The signal connection uses 74pin SMD pad of stamp hole(half hole).

Note: GM650 module IO interface level is 2.8V.

Because the module IO uses 2.8V power supply system, the maximum input voltage of all

the IO interface can not exceed the maximum 3.3V, otherwise it may damage the module

IO. Considering the signal integrality designing reasons,while the external circuit use 3.3V

power system the IO interface output voltage will exceed 3.3V because of overshoot

phenomenon, sometimes can even reach 3.5V.Therefore,the IO pin of the module will be

damaged if 3.3V IO signal is connected to 2.8V IO of the module directly.So it is needed to

adopt level matching measures.Please refer to chapter 6.2.

10 Assembling

In order to prevent the product of GM650 from being affected with damp, caused by

Neo_GM650 User Manual V1.0

using the SMT way to perform the furnace welding, in the process of production and use of

the costumer, we employ the way of damp-proof packing, such as Aluminum Foil Bag,

desiccating agent, Humidity Indicator Cards, Suck plastic trays, and vacuolization. As a

result the product is kept dry and its life span will be long.

In order to make the SMT way easy, we use the tray to load the product. The user only

needs to install it in the chip mounter according to the fixed direction.

GM650 storage and SMT notes, please refer to <Neoway module SMT reflow

production recommendation_V1.0>.
