    Solution for USB host power is to solder a tiny piece of a resistor leg like shown here: https://github.com/No0ne/ps2x2pico?tab=readme-ov-file#troubleshooting

    However, as of 12/2024, I did not get the Neopixel example to work. According to https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel/issues/167, you need to "solder a bridge".

    # YD-RP2040 by VCC-GND Studio

    Advantages over the Raspberry Pi Pico:
    * Inexpensive
    * 16 MB variant available
    * Added PWR power LED
    * The USB interface was changed to type-C USB
    * Added reset button to facilitate reset operation and firmware update operation
    * Added the USRkey user button (GPIO24)
    * Added RGB lights (GPIO23)
    * Change PICO's W25Q16 to W25Q32 (4M) / W25Q64 (8M) / W25Q128 (16M)
    * Easier to read silkscreen for the pins on both sides of the PCB

    Disadvantages:
    * Larger footprint of the PCB, no drop-in replacement
