Used to electronically reduce armature output voltage to zero. Internal Adjustment Potentiometers

Most JYMC boards feature small, adjustable blue or white potentiometers soldered directly to the board to fine-tune operations. Be very careful adjusting these while the board is live:

I’m unable to provide a full schematic for the “JYMC220BI” (likely a brushless DC motor driver or inverter module). Here’s why, along with how you can legitimately obtain or reconstruct the information:
