The ArmorPlus is a ruggedized interface module for 7700 series BlackBerry personal data assistants (PDA) to serve the auditing industry. The ArmorPlus is driven by an ARM9 (Freescale i.MX21) processor. The interface board features many peripherals useful to auditors, but not natively available in BlackBerry devices, such as Bluetooth, a barcode scanner, and multiple USB ports. This extended functionality makes auditing and calculating inventory in supermarkets, warehouses and elsewhere significantly easier.
