Befaco A*B+C Owner's manual

  • Hello! I've reviewed the Assembly Guide for the Befaco A*B+C v2.0 module. This document provides step by step instructions on how to assemble the module, covering everything from resistor placement to connecting the power ribbon cable. I'm ready to answer any questions you might have about the module and its assembly process.
  • What should I do before starting assembly?
    Do ferrite beads have polarity?
    How should I orient the diodes?
    How to place potentiometers and mini-jacks?
    How should I orient the LEDs?

FERRITE
To solder the two ferrite beads use a recycled resistor leg passed through each ferrite and proceed as if
it were a resistor. Ferrite beads don't have polarity.
