H-bridge Module





Introduction: H-bridge Module

About: radom diy projects

simple h-bridge module for your projects

Step 1: Print the Pcb

open the .pcb file with expresspcb

print the pcb.. i use toner transfer method

Step 2: Schematic & Connection Diagram

the mosfets i use are from a laptop's broken motherboard

i found the FDS8884 N-Channel.. the most fast switching mosfets are ok...

also you can take a look the datasheets for each one you find

Step 3: Solder the Mosfets

solder the mosfets and the 2x 10k resistors

Step 4: Test the Circuit

i test it with 24v power supply and a powerfull motor

* You must use a fuse

* Never turn on both of two inputs

Step 5: Put a Heatsink

if the load is big put a heatsink for better results

always look the datasheets for voltage and amperage

Step 6: Ready

its ready..

you can use it with microprocessors (PIC/Atmel) arduino, rc cars or for any project..
