PicoUART6
The PicoUART6 is an interface board providing 6 3-pin SH sockets compatible with the Raspberry Pi 5 UART and a single I2C port compatible with 3.3V STEMMA QT devices.
There are various models of the PicoUART6 available (please check which version your seller has available).
- Assembled - Supplied with Raspberry Pi Pico already fitted, firmware installed and ready to go.
- Assembled PCB Only - Solder your own Raspebrry Pi Pico either directly to the board or use socket headers on the PicoUART6 and pin headers on the Raspberry Pi Pico).
- Headers - Socket headers already fitted on the board. Fit your own Raspberry Pi Pico with Headers (or solder pin headers to a regular Raspberry Pi Pico).
The pinouts are shown in the table below (function applies when using our firmware).

If you need to program your Raspberry Pi Pico with our firmware or you wish to update it please follow the steps below.
- Hold the BOOTSEL button on the Raspberry Pi Pico and plug it into your computer.
- Wait for the drive "RPI-RP2" to show up.
- Navigate to the page with our firmware releases.
- Download the latest .uf2 file and save it to the "RPI-RP2" drive.
- Wait for the file to save.
- The Pico will restart and you should then see the PicoUART6 detected by your OS.
NOTICE:The USB CDC Serial ports will be automatically detected in recent operating systems Windows (10 and above), Linux and Mac OS X. Utilisation of the I2C port is not fully supported from within Windows. On Linux to use the I2C port you will need to load the i2c-tiny-usb kernel module. The firmware uses the PIO peripherals of the Picos RP2040 so other "Pico" compatible boards not using an RP2040 will not work.
