My Low Pass Filter for 2 Wire Fans
-
Sometimes i ve got fans which are not fully controlable. E.g. only 100 percent works. Or at 20% there is Not enought airflow Like in the datasheet. Etc.
Even changeing the frequency in M950 does not Help. In an old thread @dc42 mentioned using a Low Pass Filter and setting the frequency to 65535.
So i Made a little PCB for it
Works good. I have some in spare. Populated and Not populated.
