This project converts the Raspberry Pi Pico(or any RP2040) into a USB to 6 UART board.
This expands Noltari's project to add 4 additional UARTs using the pico PIOs. And expands on harrywalsh's project to provide better SEO and remove some data loss when using all 6 UARTs concurrently.

The pinout can easily be modified in uart-bridge.c but below is the default
| Raspberry Pi Pico GPIO | Function |
|---|---|
| GPIO0 (Pin 1) | UART0 TX |
| GPIO1 (Pin 2) | UART0 RX |
| GPIO4 (Pin 6) | UART1 TX |
| GPIO5 (Pin 7) | UART1 RX |
| GPIO8 (Pin 11) | UART2 TX |
| GPIO9 (Pin 12) | UART2 RX |
| GPIO12 (Pin 16) | UART3 TX |
| GPIO13 (Pin 17) | UART3 RX |
| GPIO16 (Pin 21) | UART4 TX |
| GPIO17 (Pin 22) | UART4 RX |
| GPIO20 (Pin 26) | UART5 TX |
| GPIO21 (Pin 27) | UART5 RX |
