A7670E LTE Cat-1 HAT for Raspberry Pi (2G/GSM/GPRS)
The A7670E Cat-1 HAT Â is an LTE Cat-1 (a 4G LTE standard for IoT) module for the Raspberry Pi, which supports wireless communication modes including LTE-TDD, LTE-FDD, GSM, GPRS and EDGE for the for Europe, Southeast Asia, West Asia, Africa, China, and South Korea regions, with up to 10Mbps downlink rate and 5Mbps uplink rate. It supports Windows/Linux operating systems and multiple network protocols. The module size is the same as SIM7000/SIM7070 series, and the AT commands is mostly compatible with SIM7600 series. It is suitable for IoT applications like remote information processing, monitoring devices, POS, industrial routers, remote diagnosis, etc.Â
Online development resources are available, which include wiring guidance and example code, with additional information being found on the product wiki and manual.
