Quectel UMTS&LTEEVB-KIT

Quectel UMTS&LTEEVB-KIT is a universal hardware evaluation platform designed to test the basic functionalities and performance of Quectel's UMTS (3G), LTE (4G), LPWA (IoT), and Wi-Fi modules.

The board does not house the cellular module directly; instead, it uses a Testing Adapter plug-in board (TE-A) that mates with the specialized headers on the main evaluation board (EVB).

Quectel UMTS&LTEEVB-KIT Specifications:

CORE TECHNICAL INTERFACES
-------------------------------------------------
* Power Supply: Powered via a 5V DC barrel jack power input or through the main USB interface.
* Cellular Module Interface: Dedicated UMTS & LTE TE-A connector pins designed to pass signal lines directly to the adapter board.
* Wi-Fi / Connectivity Extensions: Integrated Wi-Fi & Ethernet TE-A headers to evaluate companion modules.
* Data Communication:
- Main USB 2.0 interface for AT command routing, high-speed data transmission, and firmware flashing.
- DB9 Serial (RS-232) and UART interfaces for debugging and direct terminal testing.
* Audio Interfacing: Dual specialized slots to fit external digital audio codec boards.
* Peripherals: Onboard standard (U)SIM card holder and an SD card slot for massive data logging operations.
* Switches & Indicators: Hardware power toggle, reset buttons, and modular state LEDs displaying Power, Status, and Network connection metrics.
