This is a 4G/3G/2G Raspberry Pi communication HAT with GNSS positioning and high speed LTE CAT4 global band connection. By connecting it to PC, Raspberry Pi or Jetson Nano host boards, it is easy to enable 4G high speed networking, cloud platform communication, phone call/SMS, and global GNSS positioning functions.

• Supports dial-up, phone call, SMS, TCP, UDP, MQTT, HTTP(S), FTP(S), and so on
• GNSS positioning: GPS, Beidou, Glonass, Galileo, QZSS, LBS base station
• USB 3.1 port (USB 2.0 compatible) for connecting to PC, Raspberry Pi, or Jetson Nano host board to enable high speed 4G communication
• Onboard UART, PWR, and RST control pin, built-in voltage level translator, enabled via DIP switch, for use with hosts like Raspberry Pi or Arduino
• Onboard USB-C connector, enabled via switch, for connecting standalone power supply for the module, allows more loads, stable amd flexible power supply
• Onboard power supply on/off switch, reset button and LED indicator, easy to turn on/off the module or monitor the operating status
• Reserved 4x SMA to IPEX antenna interfaces, with pre-soldered 2x connectors for easily using antennas, allows changing the SMA antenna position
• Onboard audio jack and audio decoder, allows audio operation like making phone call
• High efficiency power supply circuit, up to 3A output current
