SIM900A MINI V4.0 Features:
- Diverse Power Supply Options: Comes with two on-board power supply interfaces – VCC5, which utilises a 5V power supply, and VCC4 that uses a 3.5-4.5V power supply. Both can either self-start upon powering or be controlled to start.
- Antenna Flexibility: Equipped with both SMA (default) and IPXmini antenna interfaces. The SIM900A interface has a reserved reset.
- Superior Design: Compact in size at 49*50, the module is constructed using all-new and original devices.
- Optimal Power Handling: While the computer can provide initial USB module power, it’s recommended to have a current of more than 1A for substantial data transmission. When dormant, the module consumes a mere 10MA of power.
- Broad Compatibility: Supports 2, 3, and 4G mobile phone cards. Its serial port is designed to be compatible with both 3.3V and 5V single-chip microcomputers.
- Enhanced Safety: The SIM card circuit is fortified with the SMF05C ESD chip, ensuring prolonged durability.
- Clear Markings: Every interface on the PCB displays screen printing marks for easy identification and development.
- Versatile Antenna Interfaces: Defaulted to an SMA straight head with an IPXmini antenna connector.
- Comprehensive Control Interface: All control pins are led out, complete with a detailed description for each, making it user-friendly.
