Note: From 10th Aug onwards, the wireless HAT is updated to the latest version. Compared with the old version, the new version has the following changes:
- Newly added 330uF electrolytic capacitor (Stronger voltage stabilization ability)
- Newly added PWR and Flight mode pin jumpers (Automatic power-on function can be set, and the IO port can be customized to control the switch and Flight mode)
- Add solderable pads for VCCIO.(when used with Raspberry Pi, the SIM7600X 4G HAT is soldered at 3.3V working level by default; if you need to use 5V working-level MCU, you can change it to 5V by yourself)
- Add solderable pads for the module USB. (if you don’t want to use a USB adapter cable, you can solder them to the corresponding USB solder joints at the bottom of the Raspberry Pi through some flying cables. This operation should be used with caution by non-professionals)
- The power management IC was changed from MP1482 to SPX29302
- The silkscreen naming is changed from "WPI naming" to "BCM naming"
- Fine-tuning the layout
- Add new solder joints for module Boot to burn the firmware forcibly. Short-circuit the two pads can enter the forced firmware burning mode. (Only used when the firmware cannot be burned normally)
The SIM7600E-H 4G HAT is a 4G/3G/2G communication and GNSS positioning module, which supports LTE CAT4 up to 150Mbps for downlink data transfer and it is pretty low power consumption. In simple words, this HAT (for Raspberry Pi) supports cellular communication such as SMS and also data for the Internet, and a built-in positioning sensor which is GNSS. Sometimes it is called the GSM module.
You can connect this 4G module with a computer to surf the Internet or attach it onto Raspberry Pi to enable functions like 4G high-speed connection, wireless communication, making a telephone call, sending SMS, global positioning, etc.
