• Move C7 as shown on the screenshot. When buck converter operates, the current flowing between C7 and Q2 is a square wave. If this square wave current passes through ACS712 it introduces unnecessary noise to input current readings and increases losses on Q1 (according to P=I^2*R).
  

C7 has been moved. As well C8 has been changed from Axial to Radial cap.
