Frequently Asked Questions (FAQ)
Q1. What is the difference between the EC200G-CN and EC200U-CN modules?
The EC200G-CN supports LTE Cat-1 with GNSS and a simplified design for compact applications. The EC200U-CN is a more advanced variant with higher throughput and broader regional band support.
Q2. How do I power the modem?
You can power it directly via the USB-C connector (5 V) or through an external VIN input between 5 and 26 V.
Q3. Can I use this modem with Arduino or ESP32?
Yes. The modem communicates via UART or USB-C. Example Arduino and ESP32 interface codes are available in the 7Semi GitHub repository.
Q4. Is a SIM card required for GNSS operation?
No. GNSS positioning (GPS, GLONASS, etc.) works independently of the cellular SIM card.
Q5. What antenna is included?
A 52 × 24 mm FPC antenna with IPEX (u.FL) connector, 1.13 mm coax cable, and 3M adhesive backing is included for easy installation.
Q6. Can it send data to cloud platforms like AWS or Adafruit IO?
Yes. The EC200G-CN can be configured via AT commands or a microcontroller to send data to MQTT/HTTP endpoints such as AWS IoT, Azure, or Adafruit IO.
Q7. Does it support GNSS positioning while connected to LTE data?
Yes, the EC200G-CN supports concurrent GNSS operation, allowing location data acquisition during LTE communication.
