It comes with the following features:
+
 
+
* 802.3at up to 21W(5V/4.2A)
+
* PWM control FAN up to 12000RPM
+
* Temperature sensor DS18B20
+
* Optional 40PIN GPIO pass-through exported
+
* Compatible with ROCK Pi 4, Raspberry Pi 3B+ and Raspberry Pi 4
+
* Clean design by hiding the fan and the big transformer inside
+
* EEPROM for HAT identity and driver probe
