About this item

The ELECROW Crowtail‑4G SIM A7670E is a multi‑functional cellular + GNSS communication module designed for IoT, smart devices, vehicle tracking, remote sensors, and wherever both broadband data and precise location are required. It integrates the Simcom A7670E chip, which supports LTE Cat‑1 networks, along with GPS, GLONASS, and BDS satellite navigation systems, allowing for reliable positioning in diverse geographies. The module supports voice calls, data transmission, SMS, and has standard network protocols like TCP/IP (v4 & v6), HTTP/S, FTP, DNS, etc., enabling both real‑time communication and periodic reporting. Power options are flexible: it accepts supply from a Li‑ion battery (≈3.7 V) or via USB‑Type‑C (≈5 V), with onboard power regulation. It includes a power button, SIM card slot, charging interface, 4G/GSM/LTE radio, and audio jack (for headphone + mic) for voice. Compact in form factor, the module also offers firmware upgrading over USB (or FOTA), making for easy maintenance/updates. With relatively low power consumption (given its cellular & GNSS capability), it is well suited for battery‑powered applications. It comes with 4G + GPS antennas. Overall, it makes a strong option when you need connectivity + positioning in a Crowtail modular ecosystem or with Arduino / Raspberry Pi systems.
