ESP32 EC200U-EU Development Board

Description

This modem combines an ESP32-based Wi‑Fi/Bluetooth module and a Quectel EC200U LTE Cat 1 cellular module into a compact board designed for IoT/M2M projects. The ESP32 provides dual‑core Xtensa LX6 processing, onboard Wi‑Fi (802.11b/g/n) and Bluetooth v4.2, plus rich peripheral interfaces. The EC200U delivers LTE Cat 1 cellular connectivity (up to 10 Mbps down / 5 Mbps up) with worldwide LTE/GSM coverage, GNSS optional, and compatibility with multiple Quectel module families and standard Mini‑PCIe packaging.

Features

• Cellular: LTE Cat 1 optimized for IoT/M2M, worldwide LTE/GSM support, EC200U variants for regional bands, optional GNSS, Wi‑Fi scan/Bluetooth/FOTA support.
• Wi‑Fi & BT: ESP32 supports 802.11b/g/n (up to 150 Mbps in 802.11n), A‑MPDU/A‑MSDU, and Bluetooth BR/EDR + LE (v4.2).
• Processing & Memory: Dual‑core Xtensa LX6 up to 240 MHz, 448 KB ROM, 520 KB SRAM, 16 KB RTC SRAM; optional SPI flash (4/8/16 MB) and optional 2 MB PSRAM.
• Interfaces & Peripherals: Up to 26 GPIOs, SD card, UART, SPI, SDIO, I2C, PWM (LED/motor), I2S, IR, pulse counter, capacitive touch, ADC, DAC, TWAI® (CAN compatible).
• Physical/UX: Compact unified form factor, laser‑engraved package for durability and heat dissipation; supports Mini PCIe where required.
• Drivers & OS support: USB drivers for Windows 7/8/8.1/10, Linux, Android.
• Reliability & Certs: RF and Bluetooth certifications, environmental compliance (REACH/RoHS); module tested for HTOL/HTSL/uHAST/TCT/ESD.

• Form factor: compact unified module; EC200U also available in standard Mini PCIe package.
• Software support: USB drivers for major desktop/mobile OS; FOTA capable on EC200U.

Applications

• Remote telemetry, energy control and monitoring, industrial sensors and PDAs.
• POS/POC terminals, shared equipment, data cards, security and protection systems.
• Any IoT/M2M deployment requiring both robust local Wi‑Fi/Bluetooth and reliable cellular fallback or roaming.

Benefits for Electronic Design

• Speeds development: integrated Wi‑Fi/Bluetooth + cellular on one board removes need to design separate radio subsystems.
• Easier migration and compatibility: EC200U’s compatibility with multiple Quectel families eases upgrades between 3G/4G variants.
• Rich I/O and peripherals on ESP32 let you prototype and deploy diverse sensors and actuators without extra MCUs.
• Production readiness: certified RF modules and industrial temperature options reduce certification and environmental testing burden.
• Flexible connectivity: local high‑speed Wi‑Fi with wide‑area cellular backup simplifies connectivity planning and improves product reliability.

This combined ESP32 + EC200U modem board lets you design faster and more reliably by providing integrated radios, abundant interfaces, and production‑ready module features.
