Hello
The FAQ says all pins 5v are from usb but that is not true as the schematics.
And find this because my board just stops working sundly without any reason as it was running program for couple of hours.

I just hit enter...
Does anyone had experience this before?
Thanks

Check the schematics...doesn't look like you can check the LIPO battery voltage?

Thank you for your question! In fact, on the XIAO board, both A3 and D3 point to the same GPIO, so you can use either one to connect your speaker. While the code references D3, you can also use A3 as they have the same functionality and will not affect the sound output. If you continue to encounter any issues, feel free to contact our technical support team at [email protected]. We’ll be happy to assist you further!

Hi! I have a question related to the Seeed Studio Expansion Board Base for XIAO, I use Xiao Ble Sense with NRF52840, will it fit for the SWD interface as good as XIAO SAMD21? I want to use it as SWD interface for my XAIO nrf boards without need of soldering

If you have issues like me with a xiao rp2040 + expansion board that the display is not working at all and the setup function takes minutes to execute, replace the 8x8 definition to
U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE);
