Neo_M660 User Manual V1.0 5 Pin Definition & Encapsulation 5.1 Pin Definition The signal connection uses 28pin SMD pad of stamp hole(half hole). Note: M660 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.
