4. セットアップとインストール
The A7670E-LASE development board is designed for ease of integration. Follow these steps for initial setup:
- SIMカードを挿入します: Ensure the module is powered off. Carefully insert a MIRCO SIM card into the designated slot on the board.
- 電源を接続します: Connect a USB power source (5-16V DC) to the Micro USB port on the board.
- Antenna Connection (Optional): If using an external antenna, connect it to the appropriate connector on the board.


4.1 電源オンソリューション
The module supports two power-on methods:
- Default Power-On: The product is configured for default automatic boot.
- POWRKEY Power-On Solution: For hardware developers requiring a specific power-on sequence, it is necessary to remove the material (components) with bit numbers R3 and C5 on the PWK/RST pin. This modification allows for a controlled power-on via the POWRKEY pin.
Special Note: The default automatic boot is standard. The POWRKEY boot solution requires hardware modification and is not considered a product defect.


5. 操作手順
Once the module is powered on, the Power/Network LED will indicate its status. The module can be interfaced via USB or UART.
- ドライバーのインストール: Install the necessary USB drivers for your operating system (Windows, Linux, Android) to enable communication with the module via USB.
- AT コマンド: Utilize AT commands for controlling the module's functions, such as network registration, data transmission, and voice calls. The AT command set is compatible with SIM7500/SIM7600 series modules.
- ネットワークプロトコル: The module supports various network protocols including TCP/IP, IPV4/IPV6, FTP/FTPS, HTTP/HTTPS, DNS, RNDIS, ECM, and PPP, allowing for flexible data communication.
