Hi, does the latest version of the MacAthur HAT support analog  (ie ability to read 0 -5 volts) inputs, if not could anyone recommed a suitable HAT.

I have an existing set up on an ardunio where i input the following through varios sensors and voltage dividers:

• Rudder position
  
• Oil pressure
  
• Engine Coolant Temp
  
• Fuel Level
  
• House Bat Voltage
  
• Endine Bat Voltage
  
• RPM
  

and would like to migrate all this over when I convert to running an Rpi and MacArthur HAT (has been pc based up to now!)

Google is suggesting a "High-Precision ADC HAT For Raspberry Pi (10-Channel 32-Bit)" based on ADS1263 chip, but wanted some real world experience

Thanks in advance

From the electrical perspective, this ADC HAT could co-exist with the MacArthur HAT. It uses a different pin for SPI chip-select (CS, pin 15), and pins DRDY (11) and RESET (12) are also unused on the MacArthur HAT. 
The (optional?) digital GPIO pins do overlap with the MacArthur HAT, except for pin 31. It's unclear how/if they have any function on the ADC HAT.

No idea about the software side of things.
