The **SC200D-22-R/E** is a specific variant of the Smart Module series produced by **Quectel**. It is designed for high-performance Internet of Things (IoT) applications, combining cellular connectivity with a powerful processor and an Android operating system. --- ### 1. Key Technical Specifications The SC200D series is based on the **Qualcomm QCM2290** platform. Below is a breakdown of its core electronic characteristics: | Feature | Specification | | :--- | :--- | | **Processor** | Quad-core ARM Cortex-A53 @ 2.0GHz | | **GPU** | Adreno 702 | | **OS Support** | Android 11 or later | | **Memory (Internal)** | 2GB LPDDR4X + 16GB eMMC (Standard configuration) | | **Network Support** | LTE Cat 4, 3G (WCDMA), 2G (GSM) | | **Wireless Connectivity** | Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.0 | | **GNSS** | GPS, GLONASS, BeiDou, Galileo, QZSS | --- ### 2. Physical and Electrical Interface The module utilizes an **LCC + LGA** package (Leadless Chip Carrier + Land Grid Array), which allows for high durability and ease of automated assembly. #### Major Interfaces: * **Display:** Support for 4-lane MIPI DSI (HD+ resolution up to 720 x 1600). * **Camera:** Two groups of MIPI CSI interfaces (supports up to 13MP). * **Audio:** 1x Speaker, 1x Receiver, 2x Microphones. * **USB:** USB 2.0 High Speed (supports OTG). * **I/O Ports:** UART, SPI, I2C, and multiple GPIOs for peripheral control. --- ### 3. Suffix Decoding (22-R/E) In Quectel nomenclature, the suffixes denote regional optimizations and memory tiers: * **22:** Refers to the memory configuration (typically 2GB RAM + 16GB Flash). * **E:** Denotes the **EMEA/APAC/Brazil** regional version. This version is tuned for the frequency bands used in Europe, the Middle East, Africa, and parts of Asia. * **R:** Often signifies a specific revision or a "Regulatory" compliant SKU for specific markets. --- ### 4. Typical Applications Because this part functions as a "system-on-module," it is used in devices requiring a rich UI and high-speed data: 1. **Smart POS Terminals:** Handling secure payments and inventory UI. 2. **Dashcams:** Recording high-def video while providing GPS tracking. 3. **Industrial PDAs:** Rugged handhelds for logistics and scanning. 4. **Smart Vending:** Managing touchscreens and remote telemetry. ---
