Neo_GM650 User Manual V1.0 All rights reserved by Shenzhen Neoway Technology Co., Ltd Page 5 Total 14 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. 2 Figuration Table 2-1 GM650 Figuration Specification Specifications Description Dimensions 30.0mm*24.0mm*2.7mm(length*width*height) Weight 3.7g Overview

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.

Neo_GM650 User Manual V1.0 All rights reserved by Shenzhen Neoway Technology Co., Ltd Page 14 Total 14 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>.
