Hi, I recently purchased a Luckfox Pico. And I wish to record audio via it. The website I bought it from mentioned that microphones can be added via TP5, TP6. TP6 is mentioned as MIC0_P and TP5 is mentioned as MIC1_P. Is this correct? Also TP7 is MICBIAS. I have tried connecting electet mic's P pin via a capacitor to TP5. But on recording I am not getting any sound. Also if I bypass the capacitor I get some static but no sound. Please help with the connections and which mic I should use.
