DIY soldering kit based on pixel art pikachu pal!

Here you could fine the complete project to make your own badge.

  • Schematic
  • PCB
  • BOM

It's a simple blinking LED circuit, just a couple of components , basically is an oscillator made of RC circuit. It run from a 3.0 volts cr2032 battery.

PCB details:

  • Black solder mask
  • ENIG finish
  • Thickness 1.0mm to 1.6mm ( 1 mm recommended for less weight)

PCB design contest 2020

I made this badge to practice how to solder smd parts and get a cool gadget to show.

To made this posible I used free EasyEDA designer tool from EasyEDA.com , it integrastes PCB fabrication with JLCPCB.com and source components from lcsc.com

so you will have :

  • Electronic capture / PCB LAY out / 3D modeling ( EasyEDA designer)
  • PCB Fabrication supplier ( JLCpcb.com )
  • Components supplier ( lcsc.com )
