Botboarduino Repair?

Hello I bought a botboarduino a year ago and now it is not working. I was wondering if I am able to get it repaired or if I should by a new one. The problem with the board is that if I plug 4 AA batteries into the board, it doesn’t turn on, the low dropout regulator heats up. Now if I plug the board into the computer with the USB cable (without the batteries), the board will turn on.

By the way, my botboarduino has worked before.

Thanks!

Hi,

Before changing or trying to repair the board, are you sure that all jumpers are installed correctly ? Can you post a picture of your board ?

When you say that the regulator heats up, is it hot to the point that you cannot touch it ?

Best regards,

https://mega.nz/#!OI1B0SJaYes, I have checked all of the jumpers and are all in the right place (check picture). When the regulators heats up, I am able to touch it, and the board still doesn’t turn on. Yesterday I put the batteries in and they heated up the regulator that I was unable to touch it.

Thanks!

Ok, I have looked into this more and I am pretty sure that the regulator is ruined. This is not a big deal, right? My question now is if I can replace the regulator. I have looked for signs of a damaged board and found nothing. The board looks fine, it is just the regulator.

So can I just buy a new regulator and replace it? Should it work fine? What do you think I should do?

Oh and by the way this is the regulator that I am thinking of buying (adafruit.com/products/2164). It has all the same specs as the botboarduino (the 5 volt 1.5 AMP regulator). Also does it matter if the regulator is linear or not?

Thanks!

[size=2][font=Arial]Hello, the regulator for my botboarduino is broken. I want to replace it with this one (L78055V 1.5A Voltage Regulator) from the RobotShop. It is a 5v 1.5A regulator similar to the one from the botboarduino. Will this regulator work for it?[/font][/size]

1.5A (at 5V) should be more than sufficient to power the logic voltage and whatever additional sensors you attach.
