Neo_GM650 User Manual V1.0 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.

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.
