DC Motors with BOE-BOT or BS2

thomas_pittin

Hi all,

I want to know if I can use a DC motor with BOE-BOT or BS2

How can I do?

thanks

Shouldn't be much of a problem.

Depending on voltages required, and whether you want it to run only one way, or both ways, you may be able to get away with using a transistor and a couple of resistors to drive it.

In other Words; details!

The DC motor have the following details:

Voltage: 12V (i can use a different battery to supply the Motors)
Current: 440mA

i want to drive the Motors in both ways

You require an H-bridge for each motor. There are some boards available for that size of motor.

You can even make it easier if you have some servos with damaged electronics. Use the motors in those and attach an H-bridge to replace the PWM control.

Hello,

where can I find a board?

I need to control 4 DC motors

thanks in advance

Hmmm. I previously mentioned the L293 which will work, but you buy the chip and make your own board from a blank board.

Or here is a kit

But there is also the L298 which is better and has complete kits.
