I have tried to design a board that is very small. I'm trying to use a=20
RadioShack 276-148. This board is 1 =BE inch square. All power and=20
sensors output will be done through male headers. This board has two=20
power sources. 9V Battery for the chip and 4 AA Batteries for servo's=20
or whatever.=20=20

I have a drawing in the photo area. I've included a link below (I hope=20
it works). For each I/O or ADC pin I have included 6V and Ground. My=20
goal is to connect sensors and servo's with 3 wire connectors.
My question is, will this design work? I also have an idea to add a 5V=20
regulator for the I/O pins. I could also use the 5V from the BX-24 for=20
some of the ADC pins.=20=20

I'm interested advice or suggestions. I plan to bridge the pad on the=20
circuit card.

If I get I built, I will post more pictures.

Hello Newton,
I believe the BX-24 has a upper voltage limit of 5vDC
on its I/O pins. Take a look at the current sink limits
of the I/O pins as well before interfacing to them.
Here is another excellent source of information.

Newton,

You should take a look at the atombot board from Lynx Motion. I have
used this in several projects (using BX24 and ZX24, wish there was a
zx28!) and find it quite wonderful and flexible. I really wish the
ZxBasic people would design a board similar to this but for all their
products in mind (especially the ATMega 128's). I really would like
to use something with more IO more memory and such. Heck I would
design it if I can just find someone to produce and stock it.

Another product that would be nice and you should check out is the
AXON Micro controller.

Hi,
If you want a board tailor for you projects you should design your own.
Try the EXPRESSPCB board. You can design your own board for about two board for about $80 dollars. The software is free and you can order it directly from your PC. I used to buy prototype boards until I used the EXPRESSPCB. After that I make my own board. My projects look professional . Give a try.

I think the Zbasic folks don't have a small board because their ZX-24 processors work in most boards made for the BS-2 and BX-24. With the ZX you get faster speed and more memory. If you need that you can still use your old BX-24 board and just upgrade the processor.

I built the driver board. Please see the pictures at the Photo link: http=
