4. Opsætningsvejledning

4.1 Installation af SIM -kort

Important: This product does not come with a SIM card. A MIRCO SIM card is required for cellular connectivity.

The development board features two SIM card slots (SIM1 and SIM2). By default, single SIM card operation is supported. Dual SIM card functionality is related to the specific module and firmware (FW). For details on dual SIM support, please contact customer service.

4.2 Power-On Solutions

The development board supports two primary power-on methods:

1. Default Automatic Power-On: The product is configured for automatic boot by default.
2. POWRKEY Power-On Solution (for Hardware Developers):
   • If you require the POWRKEY boot solution, please notify customer service before shipment. The manufacturer can ship the product configured as required.
   • For hardware developers who receive the default automatic boot version and wish to implement POWRKEY boot, you must remove the material (components) with bit number R6 and C26 on the PWK pin. This involves shorting 3.3V on the PWK pin.

Special Note: The default automatic boot is not considered a product defect. Modifications for POWRKEY boot are at the user's discretion and are not a reason for return based on product defects.

Please remove the material with bit number R6 and C26 short 3.3V on PWK pin for POWRKEY boot.

4.3 Module Suffix and Regional Compatibility

The module suffix indicates the applicable region for network compatibility:

• G: Globalt
• E: Europe/Middle East/Africa
• NA: North America
• C: Kina
• JCJapan
• SA: New Zealand/Australia/South America (This product, A7670SA-FASE, is for SA region)

Ensure your module's suffix matches your intended operational region for optimal network performance.

5. Betjeningsvejledning

The SIMCOM A7670SA-FASE development board is designed for various IoT applications requiring cellular and GNSS connectivity. Once powered on and a valid SIM card is inserted, the module will attempt to register with the cellular network. The LED indicators will provide status feedback (Power/Network light).

Users can interact with the module via UART, USB, I2C, and GPIO interfaces. AT commands, compatible with SIM7500/SIM7600 series modules, are used for configuration and control. Drivers for Windows, Linux, and Android operating systems are available for USB connectivity.

The integrated GNSS functionality allows for location tracking. Ensure proper antenna connection for both cellular and GNSS for optimal performance.
