Which power supply for BRAT?

Is it best to go with the L5WP-01 power supply as the WP-01 is only 5v?

Also I have a 5.5v 300ma power supply from my other Parallax bot … but that will not work as it is to low a V and amps right?

Just want to make sure I use the correct setup and not fry my SSC32 :frowning:

Either would be fine. 6v will give you a bit more torque from your servos, so I would go for that one personally.
As long as it’s between 5 and 6v for the servos, and enough current supply, you should be fine. You may need to supply the logic with a separate 9v battery or something, as those power addapters tend to drop their voltage when high current is drawn by the servos, which resets the SSC32.

So I could use my 5.5v 300ma power supply? Even if it is 300ma and not over 2amp?

No, it will not provide enough power to run the BRAT.

You’re applying the wrong logic to the problem. You can use a 4.8 to 6.0vdc supply capable of providing 2.5 amps or more… More current capability will only help the situation.
