    Note that the WS2812 Control Python script in the MicroPython Examples has the red and green reversed. I updated mine to: ar[j] = g << 16 | r << 8 | b and it works as expected.

    Also thanks for a great little board!

      Good catch... sorry, I must have been thinking RGB LED at the time. I just updated the example code to reflect the color sequence properly.

    Hey, I'm the author of the pico-setup-windows installer mentioned in this article (and in the RP2040/Pico Getting Started Guide.) Just dropping a note here to say that if anyone has issues with that installer, please open an issue on, I might not see all of the comments on this page.

    Thanks SparkFun, I've been a big fan over the years!

    Can we get a pinout diagram of what each of the numbered GP pins are capable of? I.E. which pins can do SPI tasks, i2c tasks, uart, etc?

    hello, i can't wait to get mine!

    I have a question about the Power Control circuit, why use a MOSFET instead of a Schottky diode?

      I don't see how that could work; however, if you can explain your design/thinking... I'd be happy to forward that information to the engineering team.

      Update: Ahh... I think you might be referring to using a Schottky diode between the battery voltage and the input voltage to the LDO regulator (where the drain and source for the MOSFET are connected). Maybe the engineer can chime in on that design choice. My guess is that the MOSFET method absolutely prevents reverse current into the battery and possibly creating an over voltage/charge problem.

        Can't wait to play with this, also you are awesome
