Use your Raspberry Pi with LTE Cat-4 4G / 3G / 2G Communication & GNSS Positioning, for remote data transmission/ phone/ SMS, suitable for remote area monitoring/alarming…

This 4G hat is based on the Maduino Zero 4G LTE, but without any controller. It needs to work with Raspberry PI( 2x20 connector and USB). The Raspberry communicate with this HAT with simple AT commands(via the TX/RX Pins in the 2X20 connector) for simple controls, such as SMS/ Phone/ GNSS; with the USB connecting and proper Linux driver installed, the 4G hat act as a 4G network adapter, that can access to the Internet and transmit data with 4G protocol.

Compares to normal USB 4G dongle, this Raspberry Pi 4G Hat has the following advantages:

1. Onboard Audio codec, that you can have a call directly with your RPI, or auto broadcasting with a loudspeaker;

2. Hardware UART communication, hardware controlling of Power(by 2s pulse of PI GPIO or POWERKEY button), hardware controlling of flight mode;

3. Dual LTE 4G antenna, plus GPS antenna

1. SIM7600X Module(A for E)

2. USB, for 4G data communication, connect to RPI via USB cable

3. Loudspeaker

4. Earphone/Mic, please use an earphone with a mic, for phoning

5. PowerKey. SIM7600X powered one by default as 4G hat gets powered, SIM7600X can not be powered off separately. If you want to control the SIM7600X to power on/off, please take off the R15, that the SIM7600x will not be powered on by default, but need the user to manually press the PowerKey to power On/Off the SIM7600X, or via Raspberry Pi GPIO_21, with 2s pulse

6. LTE AUS Antenna

7. LTE Main Antenna

8. GPS Antenna

9. Net Status LED

10. Communication Status LED

11. Audio Decoder

12. SIM Card Socket
