I have designed a custom HAT for the Orange Pi Zero 2W, incorporating a SIM7080G module, a GPS module, and a 52-pin PCI connector. The PCB was developed using Altium Designer, ensuring high-quality layout and performance. To enhance functionality, I added an extra antenna port for both the GSM and GPS modules and included a backup capacitor to ensure continuity for the GPS module's real-time clock. My design also supports a 5 to 12V power input and provides a lithium battery input for added flexibility. I am proficient in handling microcontrollers and GSM modules like the SIM7080G, ensuring that the design meets the required standards.
