“This is like one of the most useful shims out there. Best replacement for cheap Chinese buck converters. I opted to "permanently" solder this one onto my Raspberry pi Zero. Connected 12V 1A and *ta da* it just works! What more can I say? I'll buy more of those whenever I need more! They are amazing and you can still use the full GPIO pins if you don't solder on the separate connector. Also nice to provide 2 connector leads!!!”
