The 7Semi 4G LTE Modem is a compact cellular communication board designed for IoT, industrial automation, telemetry, remote monitoring, asset tracking, and embedded connectivity applications. Powered by the Quectel EG800AK-CN LTE Cat 1bis modem, the board provides reliable 4G LTE connectivity in a developer-friendly format with accessible power, UART, control, and status interfaces.

The board integrates a USB Type-C connector for power and modem communication, a Nano SIM card slot, LTE antenna connector, onboard power regulation circuitry, status indicators, and dedicated control pins. With support for LTE Cat 1bis networks, the modem delivers download speeds up to 10 Mbps and upload speeds up to 5 Mbps, making it suitable for cloud-connected IoT devices, industrial gateways, telemetry systems, and cellular-enabled monitoring solutions.

Designed for easy integration with ESP32, STM32, RP2040, Arduino, Raspberry Pi, Linux SBCs, and custom embedded systems, the board exposes UART communication and hardware control signals for direct modem operation using AT commands.
