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:
| Type | Connector | Size |
|---|---|---|
| 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.
