How To Make :
I designed the 775 Motor Speed PWM Controller 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 9 days. I bought the required components in the Local 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.
The best site ever seen, ckts , description with pcb layout and geber files attached. Complete in all.👍👋👋👋
