SIMA7670C FS-MCore 4G LTE Module

The SIM A7670C FS-MCore 4G LTE Cat.1 Module is a compact, industrial-grade cellular communication solution designed for IoT and M2M applications requiring reliable data connectivity. Based on the advanced SIMCOM A7670C chipset, this module delivers high-performance wireless communication with support for multiple network technologies including LTE-TDD, LTE-FDD, GSM, GPRS, and EDGE, ensuring broad compatibility across global cellular networks.

This development board features a convenient serial TTL interface for seamless integration with microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32. Communication is handled through standard AT commands, making it easy to implement SMS messaging, TCP/IP data transfer, HTTP/HTTPS requests, FTP file transfers, and real-time GPS/GNSS location tracking. The module achieves impressive data speeds of 10Mbps downlink and 5Mbps uplink on LTE networks, with fallback support to GSM/GPRS at 85.6Kbps for areas with limited 4G coverage.

The integrated IPEX antenna connector accepts standard 4G LTE antennas (included) for optimal signal reception, while the clamshell-type Nano SIM card holder provides secure and convenient SIM installation. Dual LED indicators display power status and network connectivity at a glance, eliminating guesswork during development. The compact 28mm × 26mm PCB footprint makes it ideal for space-constrained projects, while the wide operating voltage range of 5-16V DC and industrial temperature rating (-40°C to +85°C) ensure reliable performance in harsh environments.

Perfect for remote monitoring systems, GPS vehicle tracking, smart agriculture sensors, industrial automation, environmental monitoring stations, alarm systems, smart metering, vending machines, asset tracking devices, and any IoT project requiring cellular connectivity. The module supports comprehensive network protocols including TCP/IP, IPv4/IPv6, Multi-PDP, FTP/FTPS, HTTP/HTTPS, and DNS, enabling flexible integration with cloud platforms and web services. Includes onboard UART logic level conversion with VDD reference voltage connection for safe interfacing with 3.3V and 5V microcontrollers.
