SIM A7672S 4G LTE TTL Modem with GNSS + BLE

Product Overview:

SIM A7672S 4G LTE TTL Modem with GNSS + BLE is a Cat-1 Module which supports wireless communication modes of TDD/FDD. consequently It supports maximum 10Mbps downlink rate and 5Mbps uplink rate.  Correspondingly AT instructions are used to communicate with the A7672S.

The Board is designed keeping in mind the requirements of the user as an illustration. It has various pinouts from the module, such as RING – used to detect incoming call, DTR – to use the 4G Module in ultra low power sleep mode, STATUS – to detect the status of 4G Module, NETLIGHT – in case developer wants to use external LED to indicate network status, RESET – developer can use this pin to connect with MCU and reset the module if required. It has onboard UART Logic Level Convertor and works on 5V TTL logic level as well as 3.3V TTL Logic level, By default its 5V TTL Logic level, in order to perform the board on 3.3V TTL Logic level please shift the 0E Resistor from 5V to 3.3V as depicted in the image.
