Google said in a blog post that the Asus Chromebit would be arriving mid-year with a low price tag.
"Smaller than a candy bar, the Chromebit is a full computer that will be available for less than $100," Google said.
"By simply plugging this device into any display, you can turn it into a computer. It's the perfect upgrade for an existing desktop and will be really useful for schools and businesses."
The statement offered no other details on the device, but Google also announced its lowest-cost Chromebook laptop computers at $149 in partnership with Chinese electronic groups Haier and Hisense.
With a display of 11.6 inches, the Haier computer is being sold through Amazon and the Hisense PC through Walmart.
