Hi,
Is the mighty hat compatible with raspberry pi 4?  :)

It just got released (https://www.raspberrypi.org/blog/raspberry-pi-4-on-sale-now-from-35/).
I see a 1.2 amps of current draw at full CPU throttle. I have not tried a Pi4 yet, hard to keep up with all these new releases.
Since it powers the Pi directly through the header, it should be just fine.
There may be some new requirements to the shutdown scripts. I will look at that when I get a chance.

Hi,
I'm about to test Pi4 with Mighty Hat.
One question about power supply. Pi4 is using USB-C type power supply.
The specs:
5V DC via USB-C connector (minimum 3A*)
5V DC via GPIO header (minimum 3A*)
* A good quality 2.5A power supply can be used if downstream USB peripherals consume less than 500mA in total.


And I have original power supply adapters:
- 5.1V, 2.5A micro USB
- 5.1V, 3A USB-C

Should I be fine with the 2.5A adapter (Pi is used for gateway server, I'm not using any usb devices)? Or should I buy USB-C to micro USB converter and connect 3A adapter to mighty hat?

Pi4 with MightyHat is up&running, so far no problems detected.  :)
