Introduction: H-bridge Module
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
you can use it with microprocessors (PIC/Atmel) arduino, rc cars or for any project..
We have a be nice policy.
Please be positive and constructive.
