有没有人用过什么体积超级小的稳压块呢，3.3V输出的最好，给推荐几个吗

测量电感充放电时间即可得到电感量。


You don't need a mcu for that. I posted quite a few schematics using the same approach but with gates.

the reading is not very stable and definitely requires averaging multiple readings, for practical uses. and it requires calibration.

google "lehman inductance meter" (named after the guy who invented it some 60+ years ago).

the same approach can be used to measure capacitance as well.
