Tibbits With "Special Needs"

Most Tibbits happily work with simple control (GPIO) lines of the CPU. Some, however, require dedicated I/O functionality from the CPU lines:

• [SER] Tibbits that require TX and RX UART lines
• [INT] Tibbits that require an interrupt line
• [POE] Tibbits that require PoE power lines
• [CAN] Tibbits that require CAN functionality
• [AUD] Tibbits that require audio functionalily
• [MMC] Tibbits that require MMC (SD) functionality
• [USB] Tibbits that require USB functionality
