  • Quick Start Guide

    Hardware Preparation

    • Step 1: Required Items

      • Development board
      • USB-C cable (A-to-C)
      • Windows 10 PC
      • Nano-SIM card
      • 4G antenna

    • Step 2: Antenna & SIM Installation

      • Attach the provided antenna to the MAIN antenna port.
      • Insert the SIM card into the Nano-SIM slot.

    • Step 3: Connect the Board

      • Connect the development board's Type-C port to a computer USB port using a USB Type-C cable to supply power. Before powering on, ensure to short the VUBS EN, VDD_EXT EN, and VBAT EN jumper pins.

    • Step 4: Power On

      • Press and hold S1 until the power indicator light (labeled D1 on the board) on the main board illuminates. If PWK_ON has been shorted in the previous step, there is no need to press and hold the power key, as the system will boot automatically.

      For detailed information regarding the development board's indicator lights and power settings, please refer to the specifications document.

    Driver Installation

    1. Download the QuecPython USB Driver from QuecPython Official Drivers.
    2. Extract and run setup.exe or setup.bat.
    3. Verify installation in Device Manager (look for "Quectel USB" ports). Ignore unrelated devices like "Mobile ECM Network Adapter."

    Tool Installation

    1. QPYcom: Download from QuecPython Tools. Extract and use directly.
    2. VSCode Plugin: Search for "QuecPython" in the Visual Studio Code marketplace.

    Firmware Burning

    1. Firmware Download: Get the latest QuecPython firmware from QuecPython Firmware Page.

    2. Burning Steps:

      • Open QPYcom, select the USB REPL port, and create a new project.
      • Choose the .bin firmware file
      • Set mode to "Download FW" and click Download.
      • For BG95, enable DM serial port before burning.
