The data sheet (if you can call 1115 pages a 'sheet') is here: https://ww1.microchip.com/downloads/en/ ... 01882F.pdfHow do I configure GPIO pins for "high drive strength mode"? I haven't read anything about that.
See the last post in this thread for how to set the drive strength: https://forum.arduino.cc/t/are-the-zero ... t/404930/7
Yes - provided that your MOSFET is designed to work at 3.3v logic levels. Many need 10v or more to fully turn on. Our N-channel power MOSFET will work at 3.3v. It is way overkill for a 30mA load. But it is easy to work with and requires no resistor on the gate:Can I use a mosfet with the gate connected directly to the GPIO, with no intervening resistor?

You would need just one channel of the circuit shown here: https://learn.adafruit.com/rgb-led-strips/usage
