Tools Needed :

  • Soldering Iron
  • past
  • lead
  • PCB Holding Stand
  • Soldering Iron Stand

How To Make :

First I designed the Amplifier Circuit on the Easy Eda website and created the gerber file. I uploaded this gerber file on the JLCPCB website and ordered 10 PCB which costs 2 dollars. PCB was delivered in 8 days. I bought the required components in the Electronic Shop and then I put all the components in the PCB and then soldered using the soldering iron and then cut the Excess Terminal and cleaned the PCB.
