Velleman MK131 Operating instructions

  • Hello! I have analyzed the provided user manual for the Soldering Project MK131. This document includes detailed instructions, diagrams, and parts lists to guide you through the assembly process. It covers key steps such as soldering resistors, diodes, capacitors and other components and the proper placement of components on the board. I am ready to answer any questions you have about this project.
  • What is the value of resistors R1, R2, R3, and R4?
    What type of diodes are used in the project?
    What is the IC used in the project?
