4G LTE Modules for Transparent Transmission

Introduction

4G Module EOT-LTE-7S4 is used to transmit data between serial port and network server by Operator network. It is configured by AT Command and work in dual transparent transmission mode.
EOT-LTE-7S4 is in small size, which is widely used in LTE, WCDMA, TD-SCDMA. It works in transparent transmission mode and more functional software. It has high speed and less time-delay , supports FTP protocol.
EOT-LTE-7S4 is compatible with 2G module 7S2/7S3, user can replace 7S3 easily. We add Watch dog function in firmware to ensure the stability if work for a long time.
