A7672S TTL Modem- 4G LTE with GNSS and BLE For IOT
₹1,600.00 excl GST
Package Includes: A7672 TTL Modem with 4G Antenna and GPS Antenna
The SIM A7672S 4G LTE TTL Modem with GNSS and BLE is a Cat-1 module that supports TDD/FDD wireless communication, offering a maximum downlink speed of 10 Mbps and an uplink speed of 5 Mbps. Communication with the A7672S module is achieved using AT commands.
The board is designed with user requirements in mind and includes multiple pinouts for various functionalities. These include the RING pin for detecting incoming calls, DTR for enabling ultra-low power sleep mode, STATUS for monitoring the module’s operational state, NETLIGHT for connecting an external LED to indicate network status, and RESET for MCU-controlled module resets. It features an onboard UART logic level converter and operates on a default 5V TTL logic level, with support for 3.3V TTL logic level. To switch to 3.3V TTL logic, the 0E resistor must be shifted from 5V to 3.3V, as illustrated in the provided diagram.
