Google announced Monday that it has signed a $5.5 billion deal with MundooBuild, a hardware startup that builds custom software for developers.

The announcement was made during Google’s I/O developer conference in San Francisco, where Mundo Build unveiled its hardware, called Mundo, that includes a new desktop and tablet, as well as a laptop.

Google’s announcement was met with a mixed reception from developers, who noted the company’s commitment to open source hardware.

“Google has long recognized the importance of open source software, and this agreement represents a significant milestone in that effort,” Mundo said in a statement.

The deal also marks the company the second major hardware manufacturer to invest in Mundobuild, joining Asus.

The company previously partnered with Google for its Chromebooks.

“This is an exciting time for Mundo and for the hardware community as a whole,” Munde said in the statement.

“MundoBuild’s innovative design will enable our customers to bring the best of Android to the web.”
