Whats is Quectel EC200U ?
Quectel EC200U is a series of 4G LTE CAT1 module, specifically optimized for M2M and IOT applications where 4G and 2G technologies are required at the same time. It can automatically switch to 2G network when 4G is not available and then switch back to 4G when possible. So this feature makes this module very handy and useful for many projects who require stable connection. This module can deliver up to 10Mbps down link and 5Mbps maximum up link due to it’s CAT1 technology. This module also comes with Mini PCIe standard form factor to make it more convenient to use on some projects.
The EC200U divides into 3 different models based on Region :
- EC200U-CN
- EC200U-EU
- EC200U-AU
🔗Tip
On eicut.com, we usually offer products with EC200U-EU as the default option, but it can be customized due to your needs.
Also this module offers in 3 models based on functionality which is indicated below :
- EC200U-EUAA : the complete one, with internal GNSS/GPS and BT/Wifi-Scan supports.
- EC200U-EUAB : With BT/ WiFi-Scan support, but with out GNSS/GPS
- EC200U-EUAC : No BT, no WiFi scan, no GNSS support
It should be noted that all above versions are completely Pin2Pin and compatible on both Hardware and Software aspects .

FAQ – Introduction Quectel EC200U LTE/4G/BT/GNSS module
What is the Quectel EC200U series?
The Quectel EC200U is a compact, low-power 4G LTE Cat.1 module optimized for M2M and IoT applications, supporting both 4G LTE and 2G fallback for reliable global connectivity.
What is the maximum data speed of EC200U?
Up to 10 Mbps downlink and 5 Mbps uplink in LTE Cat.1 mode, making it ideal for cost-sensitive IoT applications needing reliable 4G performance.
What are the different regional variants of EC200U?
• EC200U-CN: Optimized for China and Asia-Pacific
• EC200U-EU: Europe, Middle East, Africa, Australia
• EC200U-AU: Australia and Latin America
All variants are pin-to-pin compatible.
What are the different functionality variants of EC200U?
• EC200U-EUAA: Full version with GNSS + Bluetooth + Wi-Fi Scan
• EC200U-EUAB: Bluetooth + Wi-Fi Scan (no GNSS)
• EC200U-EUAC: Basic version (no GNSS, no BT, no Wi-Fi Scan)
All variants share the same hardware/software compatibility.
Does EC200U support fallback to 2G?
Yes — it automatically falls back to GSM/GPRS when 4G coverage is unavailable and switches back to 4G when signal returns, ensuring stable connectivity in rural or transition areas.
What form factor does EC200U use?
Standard Mini PCIe form factor, making it easy to integrate into existing Mini PCIe slots on routers, gateways, or custom designs.
Does EC200U support GNSS and Bluetooth?
Yes — optional in EC200U-EUAA (GNSS + Bluetooth 4.2 + Wi-Fi Scan). Other variants (EUAB/EUAC) omit some or all of these features.
What programming options does EC200U support?
• Standard AT Commands
• QuecOpen (C programming)
• QuecPython (Python scripting)
Ideal for custom IoT applications.
What is the typical power consumption?
Very low-power: 12 μA in power-off, 1.4–1.7 mA in LTE sleep, 13–28 mA in idle — excellent for battery-powered IoT devices.
What interfaces does EC200U provide?
Rich interfaces: USB 2.0, UART, I²C, SPI, PCM audio, ADC, GPIO, analog audio, and optional GNSS/BT.
