THE TINY LOW-COST Raspberry Pi computer has had a slight revision six months after launch, gaining mounting holes for the circuit board and enabling it to be powered by USB, among other changes.
In a posting to the Raspberry Pi blog, Eben Upton, executive director of the Raspberry Pi Foundation disclosed that the updated 2.0 Raspberry Pi circuit board will be rolled out over the next few weeks, incorporating some changes made due to user requests.
These include mounting holes in the circuit board to facilitate mounting the device in automated test equipment or fasten the Raspberry Pi into a case or enclosure.
Resettable fuses protecting the USB ports have now been removed, making it possible to power the Raspberry Pi from a USB hub that feeds back power, but with a warning that such a hub should not deliver more than 2.5A under fault conditions.
A reset circuit has been added, but this is not currently connected to anything. Users wishing to use this need to fit an appropriate header to connector P6 on the circuit board and short pins one and two to hard reset the Raspberry Pi - this will typically be done by wiring a reset button to the two pins.
Other changes affect some of the general-purpose input/output (GPIO) signals from the Broadcom ARM processor to the external connector headers.
A missing debug signal (ARM_TMS) is now routed to P1 header pin 13, while the primary and secondary I2C interface channels have now been swapped over, and a new connector site P5 has been added which provides an additional four GPIO signals for hobbyists to use. µ
Oh and it'll also help give aural pleasure
But it might still not be enough to make virtual reality super appealing
And a ridiculous competition
Now you can talk to your silly-looking earbuds too
