Description
Overview
The SIMCom A7683E is an LTE Cat-1bis module in a compact LGA package, for projects migrating from 2G to LTE. It delivers up to 10 Mbps downlink and 5 Mbps uplink across B1/B3/B5/B7/B8/B20/B28, stays AT-command compatible with the SIM800 series, and supports migration planning across related SIMCom modules. Check the hardware design, pin assignments, power supply and firmware before replacing an existing module.
