## Overview

The SC20 is a series of new-generation multi-mode LTE Cat 4 smart modules measuring 40.5mm × 40.5mm × 2.8mm. It contains five variants with built-in Android OS and five variants with built-in Yocto Linux OS.

The SC20 is suited to both industrial and consumer applications requiring high data rates and high-speed internet access. It delivers data rates of up to 150Mbps downlink and 50Mbps uplink on LTE networks, and supports wireless communication via IEEE 802.11a/b/g/n and BT 4.2 LE. It is also backward-compatible with EDGE and GSM/GPRS networks, ensuring connection even in remote areas without 3G or 4G coverage. Multiple-input multiple-output (MIMO) technology allows the SC20 to greatly minimize errors and optimize data speeds. The series also combines high-speed wireless connectivity with embedded multi-constellation and a high-sensitivity GNSS (GPS, GLONASS, Galileo and BeiDou) receiver for positioning.

A wide range of supported interfaces (including LCM, camera, touch panel, MIC, SPK, UART, USB, and I2C) allow the SC20 to serve a wide range of IoT applications including such as MID, PND, POS, router, data card, in-vehicle solutions, digital signage, smart safety and industrial PDA.
