Is it possible to make a voice call with this HAT?
This HAT does not have an audio codec, as a result, it lacks a voice calling feature. That is without the audio codec(audio circuit) the call will not send or receive any sound.
Is it possible to have another HAT or sensor above this HAT?

Which versions of the Raspberry Pi are HAT compatible with?
The HAT is compatible with all Raspberry Pi which contains 40W GPIO header.
What is the difference between the power and disable GPIO pins?

Are any additional components required to be added to get GPS to work or is all that included in the board?
You will need a passive GPS Antenna. It also works with active GPS antenna but needs small soldering on the board.
Can I use active GNSS/GPS antenna with the HAT?
Yes, an active GNSS/GPS antenna can be used with the HAT. In order to use it, you will need to solder the active antenna Enabling jumper (SJX) as here.
Can I power both Raspberry Pi and the HAT only through the Raspberry Pi USB power supply?
