Is this compatible with the Arduino Giga? If so, what are the pin locations for each zone if using the Giga? https://docs.arduino.cc/resources/pinouts/ABX00063-full-pinout.pdf
Here's what chat GPT had to say about this based on the schematics (take it with a grain of salt):
Zone 1
J8 (Power)
2: IOREF = 3V3
3: RESET
4: 3V3
5: 5V
6: GND
7: GND
8: VIN
J11 (Digital top)
1: D21 (SCL)
2: D20 (SDA)
3: AREF
4: GND
5: D30
6: D29
7: D13 (SPI5 SCK)
8: D12 (SPI5 CIPO)
9: D11 (SPI5 COPI)

TonyGomez My goal is to add this: https://www.dfrobot.com/product-1060.html and this: https://www.mikroe.com/click-shield-for-arduino-uno on the expansion shield but this microSD https://www.mikroe.com/microsd-click needs to be exposed to SPI pins. I was hoping to use the stepper motor driver shield's exposed analog and PWM pins but I don't think the Giga's pins line up for this.
