HAT's

 

  • Sense Hat; Acceleratometer, Magnetometer, Air Pressure and a few more
  • Automation Hat; plug and play with different type of outputs.
  • Pimoroni Unicorn; Just a led matrix hub, I don't like them a lot because you have tu put very close to the raspberry.
  • Adafruit Servo; as the name tell, control your step and servo motors.
  • pHat Beat; just a little Sound board.
  • HifiBerry DAC; co convert the digital signal to analog.
  • PoE Hat; if you would like to power on your raspberry over the internte, you need this. it's in my wish list.
  • Cluster Hat;to create server cluster
  • Uptime UPS; A funny solution to use as a external battery to protect and power your raspberry if there is any cut in the main power supply.
