Pico UART Bridge turns a Raspberry Pi Pico or Pico 2 into a dual USB to UART adapter. The computer sees two serial ports, each wired to one of the Pico's hardware UARTs, with any baud rate you set in the terminal. Handy for router consoles, flashing other boards or watching two devices at once. Original project by Noltari on GitHub, MIT. Chipnik hosts the release binaries unchanged so you can flash them from the browser.
UART0 is on GP0 and GP1, UART1 on GP4 and GP5. The Pico works at 3.3 V; use a level shifter for 5 V devices.
Firmware files come from the v4.3 release.
After flashing
- The board restarts by itself when flashing is done.
- If nothing happens, press the RST (EN) button once.
