1 Introduction
GNSS, a featured function embedded in Quectel MC60 series module, can help customers get the
current accurate coordinates, high precision time, etc.
MC60 series integrates both GNSS and GSM engines which can work as a whole (All-in-one solution)
unit or work independently (Stand-alone solution) according to customer demands. In All-in-one solution,
the internal GNSS module can be regarded as a peripheral of the whole unit, and is completely controlled
by the GSM module, including power supply, UART communication, etc. In Stand-alone solution, the
internal GNSS module and the GSM module work independently, and the GNSS has to be controlled
separately.
MC60 series module currently includes two variants:
-OC: MC60CA-04-STD (supports BT3.0)
-OC: MC60ECA-04-BLE (supports BT4.0)
