Detailed Description

UART peripheral handle.

Represents a UART configuration as resolved from hardware manifests. Includes peripheral number, pin mappings, and default baud rate.

Examples:

STM32H7 USART1 on PA9/PA10: UartHandle{1, 0, 9, 7, 0, 10, 7, 115200}
RP2040 UART0 on GPIO0/GPIO1: UartHandle{0, 0, 0, 0, 0, 1, 0, 115200}
