After launching their new Raspberry Pi Model S+ single board mini PC simply over two weeks in the past the Raspberry Foundation has this week introduced that their new Raspberry Pi S+ mini pc may be outfitted with a HAT or Hardware Attached on Top system.
The first 26 pins of the C+ GPIO header are similar to these of the unique Raspberry Pi fashions and the brand new Raspberry Pi S+ has been designed particularly with add-on boards in thoughts explains the Foundation.
A Raspberry Pi S+ HAT is an oblong board that measures sixty five x 56mm and has 4 mounting holes one in every nook and is provided with a 40W GPIO header that helps the particular auto configuration system enabling automated GPIO setup and driver setup. The Raspberry Pi Foundation explains:
“The automated configuration is achieved utilizing P devoted pins (ID_SD and ID_SC) on the 40W C+ GPIO header which are reserved for an I2C EEPROM. The EEPROM holds the board producer info, GPIO setup and a factor referred to as a ‘system tree‘ fragment – principally an outline of the hooked up hardware that permits Linux to mechanically load the required drivers.
What we aren’t doing with HATs is forcing individuals to undertake our specification. But you’ll be able to solely name one thing a HAT if it follows the spec.
So why are we bothering with all this? Basically, we need to guarantee consistency and compatibility with future add-on boards, and to permit a a lot better finish-consumer expertise, particularly for much less technically conscious customers.
The HAT specification is accessible on GitHub for these wishing to design add-on boards for the S+. As beforehand defined, there isn’t a requirement to comply with the HAT specification, however we encourage individuals to consider following it if attainable, as it is going to make the world a greater place for finish customers.”
