Handspring has posted on its site a software upgrade for the Treo 90 that allows it to use Secure Digital Input/Output (SDIO) expansion cards. These cards add functions such as Bluetooth, 802.11, GPS, presentation display, or digital imaging.
There are currently two SDIO expansion cards available, though more are in development. One is MARGI System’s Presenter-to-Go, which connects the Treo 90 directly to digital LCD projectors or other VGA devices to show business presentations. Presenter-to-Go includes software that allows for slide presentation from any printable Windows application including PowerPoint, Word, and HTML.
The other expansion card available now is the Palm Bluetooth Card. This card lets people wirelessly link a Treo 90 to any other Bluetooth-enabled device within a 30-foot radius. For example, a customer could use the Treo 90 with a Bluetooth-enabled mobile phone to wirelessly access the Internet and email.
Expected before the end of the year are an 802.11 wireless networking SDIO card and a digital camera.
This update will reflash the Treo 90’s ROM, which will make the update a permanent part of the operating system.
