These computers in sticks look pretty much identical although one is completely fanless providing a much quieter experience.
The Zotac ZBOX PI220 has a “SmartFan” cooling system and measures 5.2 x 1.7 0.62-inches. The fanless ZBOX PI221 is a bit thicker, at 0.67-inches to allow extra room for air flow.
Each model has an HDMI connector, 10/100 Ethernet jack, USB 3.0 port, 802.11ac WiFi, Bluetooth 4.0, and a micro SDXC card reader. There’s also a micro USB port for power and a detachable external antenna.
According to Zotac:
The ZOTAC PI221 features an innovative all metal chassis engineered to cool efficiently and effectively while still retaining the ultra-compact form factor.”
The PI221 was awarded with the 2016 d&i awards (Best in Computers and Systems) by the iF World Design Guide. The ZOTAC ZBOX PI220 and the award winning PI221 will be displayed at the upcoming Taiwan Computex 2016.
