这个风扇接官方的风扇插口 Raspberry Pi OS 里面会在温度达到设定值时运行。
below 50°C, the fan does not spin at all (0% speed)
at 50°C, the fan turns on at a low speed (30% speed)
at 60°C, the fan speed increases to a medium speed (50% speed)
at 67.5°C, the fan speed increases to a high speed (70% speed)
at 75°C the fan increases to full speed (100% speed)
kali 的话不清楚怎么设置。
官网看了一下,没有给出 PWM 和 Tach 引脚的编号。
