2.0 Laptop and Portable Devices
2.1 Identify the fundamental principles of using laptops and portable devices
Mini PCI is a standard for a computer bus for attaching peripheral devices to a computer system bus, similar to Peripheral Component Interconnect (PCI) bus in a desktop computer. It was specifically designed for laptops and other portable devices. Specific details of connector type and respective sizes are as given below:
|IA||100-Pin Stacking||7.5 × 70 × 45 mm|
|IB||100-Pin Stacking||5.5 × 70 × 45 mm|
|IIA||100-Pin Stacking||7.5 × 70 × 45 mm|
|IIB||100-Pin Stacking||17.44 × 78 × 45 mm|
|IIIA||124-Pin Card Edge||2.4 × 59.6 × 50.95 mm|
|IIIB||124-Pin Card Edge||2.4 × 59.6 × 44.6 mm|
The standard size for Mini PCI cards is approximately 1/4 of their full-sized counterparts. Unlike PCI cards, Mini PCI cards are generally limited in the functions they may perform. Mini PCI cards have a 2W maximum power consumption, which also limits the functionality that can be implemented in this form factor.
Available mini PCI devices include WiFi, modems, sound cards, SCSI, IDE/ATA and SATA controllers. You can use regular PCI cards with your Mini PCI-equipped hardware and vice-versa, using Mini PCI-to-PCI and PCI-to-Mini PCI adapters.
