Just...don't do it!\u003c\/p\u003e\n\u003cp\u003eYou could use this with a Raspberry Pi Pico though, as that board is rated to 5.5V.

The UBEC has built-in filter capacitors on the input and output, but it's a switching supply so it's a little noisy compared to a linear regulator.\u003c\/p\u003e\n\u003ch2\u003eResources\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat goes where?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBare wires = input\u003c\/li\u003e\n\u003cli\u003ePin header end = output\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDatasheet\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\nAdafruit pulled the heatshrink off of a similar one and found an MP2307 you can check the datasheet for conversion efficiency and other specifications.
