Motor controller 3 outputs h-bridge 20AMPS, 5V supply
This listing is for one (1x) H-bridge motor controller with 3 outputs, TTL / 5v CMOS logic level inputs, switching capacity of 20 amps at 12 volts, the board can handle 20amps continuously without a problem. The on-board charge pump permit the use of a single 5v supply. Perfect for small automation project, robotics, ect. Now you can drive very high load using your Basic-Stamp or microcontroller with this module!!
* 3 NEC EP2-3N1S H-bridge relays with contact rating of 25 amps @ 16volts
* The on-board boost converter make the relays works with a 3 to 10 volts supply
* Very small footprint of 2.13" x 2.13" x 0.9", with 4x 1/8" mounting holes
* Common supply for the 3 h-bridges outputs
* 2 logics inputs control each h-bridge:
* Input FWD/REV = 1, input BRAKE = 1, the motor is running forward
* Input FWD/REV = 0, input BRAKE = 1, the motor is running backward
* Input FWD/REV = 1 or 0, input BRAKE = 0, the motor is braking (Motor leads are shorted together)
* TTL / 5v CMOS Inputs levels
* 500ma @ 5v maximum with 3 energized relays coils
* Maximum of 20 amps through the common supply.
***Each unused input should be tie to ground and avoid leaving input pins floating, relays will be switch on and off by noises.***
