The A7670 series is the LTE Cat 1 module that supports wireless communication modes of LTE-TDD/LTE-FDD/GSM/GPRS/EDGE. It supports a maximum 10Mbps downlink rate and a 5Mbps uplink rate.
The A7670 series adopts an LGA form factor and is compatible with SIM7000/SIM7070 series(NB/Cat Modules), and SIM800A/SIM800F(2G modules), which enables smooth migration from 2G/NB/Cat M products to LTE Cat 1 products, and greatly facilitates more compatible product design for the customer needs.
The A7670 series supports multiple built-in network protocols, supports drivers for main operation systems(USB driver for Windows, Linux, and Android, etc.), and software function, AT commands are compatible with SIM7500/SIM7600 series modules.
Meanwhile, the A7670series integrates main industrial standard interfaces, with powerful expansibility, including abundant interfaces such as UART, USB, I2C, and GPIO, which is suitable for main IOT applications such as telematics, surveillance devices, POS, industrial routers, and remote diagnostics etc.
