How to make 293D dual motor driver module at home

Here I describe you how to make dual motor driver module for arduino ,Raspberry pi & other MCU
usually we use this module to make Robot

I use Home made PCB witch is drawn by marker Pen But you can use Laser Printer & toner transfer 
method.
 

  Parts List :-


  1. L 293D IC
  2. 100 mf/25v - 2pcs
  3. Resistor 220 ohm & 1K
  4.  terminal block - 2pcs
  5. male header pin 
  6. Copper clad board 4X5cm & ferric chloride  or PCb etching powder
  7. LED red & green

Making PCB using marker pen-


  Make hole using PCB drill

                                           Draw this pattern on copper side using marker pen

Now sink it in ferric chloride solution  

If  you want to know more details please watch this video 

Making PCB using laser printer :- 


Save & Print this PCB layout on an A4 glossy photo paper using laser printer

Use toner transfer method for PCB etching
