Help with Atom Pro 40 Pin!

Hi everyone! I received a BASIC Atom Pro 40 pin IC the other day from a friend with a development board but it’s a bit too big for my robot. I wanted to ask if there were any circuit designs that I could use to make it control servos (nothing flashy, just something simple but does the job).

I drew up this one but I’m not sure if it’ll work (the part of the circuit in the black box is a 6V regulator):

I don’t know of any boards out there. I took a look awhile ago and decided it probably would not make sense to come up with some new one. As the Bap40 goes for $70 and if the board costs thee same as BB2: $25 the cost is $95, but you can buy the Arc32 for $90…

As for your board, it looks to me like the pins on the top have both Power and Ground running to the ground… Not sure if you need 6v regulator, I guess it depends on what battery or the like you connect.

Ok, well I’ve got the Atom Pro 40 anyway so I’ll work on changing the circuit board so that it actually works :mrgreen:. The regulator was just so I could choose any battery pack.

Thank you for your help! :smiley:

You might add some bypass caps.

But for $25, I’d just buy a BB II. There’s a lot of work that went into it. Jumpers where you need to make choice on which power, bank, LEDs, PBs, etc.

Probably, because his post says he has a Atom Pro [size=150]40 Pin[/size], but the Bot Board II is for the Basic Atom, or any other [size=150]24 or 28 pin[/size] microcontrollers, it is not for a 40 Pin.

OK, 40 pin, that would be a little hard to use in a 28 pin socket!

Maybe try a board from BM?

I’ve got the development board but it’s quite big and that would be annoying to try fitting into a robot (I’d have to make the main body pretty big) that’s why I asked for an alternative or that maybe I could design a smaller one but no luck so far unfortunately :cry:.

Do you have the schematic for the development board? Trim off what you don’t want, and use that for a starting point. The main difference between the three models are the number of I/O pins. I’ll bet that the dev board schematic would be all you need. Or look at the BB II board.

Draw it up, we can kibitz.

Thank you for the help but a friend of mine has designed the circuit board for me so it should be ready to make in a day or so (I haven’t got access to the technology to make it at the moment). Once it’s made, I can start some work on my next robot project - a Praying Mantis Robot! :mrgreen:

Thank you again for the help! :mrgreen:

Here’s the circuit my friend designed (I thought I’d share it if anyone else needed something like this, it’s pretty basic but I think everything is there):

P.S. It’s got a regulator in it as well.
