Review on 📶 SIM7600A-H 4G/3G/GNSS HAT Module for Raspberry Pi Zero/Zero W/2B/3B/4B/Jetson Nano: LTE CAT4, 150Mbps, GNSS Positioning by Kuldip Roberts

I have not currently used this with my Raspberry Pi as I have been testing AT commands on my computer. Note that you should search for SIM7600A AT command list as not all AT commands you find on google will work. I would like to point out one thing as I'm not sure if it's a board issue, misconfiguration or something else, but I get errors when I type commands and if you were to send the same command again, would it work fine. Also, sometimes I received corrupted data when sending text messages. An example would be "Hello?o? World" when it should just be "Hello World". It could just be UART issues or buggy firmware, but I'll let you know if I can fix it.
