motherboard

Does anyone know of a cheap, non-programmable, and simple motherboard that support the BS2? Also, can you use it in your robots if you plan to sell them?

Why not look into OEM BS2s? Maybe you don't need any board, just connect the wires to a Single In Line plug.

It can be hard to navigate the Parallax site.

I like the Super Carrier board: http://www.parallax.com/detail.asp?product_id=27130

$20 pre-built. Add a BS2 and you're good to go. You can do slightly better if you build your own, but most custom board shops are going to charge you $10 to $20 for a bare board. Add a few sockets and parts, and you can top $20 per board pretty quickly. Now, if you're building thousands, then buying parts in bulk makes more sense. Even then, give parallax a call, they might be able to cut you a deal.

There's a few robot vendors who sell the BOE board along with their robots, so I don't think redistribution is a problem.

Also, note that the OEM board version of the BS2 is available : http://www.parallax.com/detail.asp?product_id=27291

And it's on special. For $30 you get a BS2 AND the board -- just add wires.

The super carrier board is nice, but I don't see where the servers plug in, and i would perfer a board that already has a soderless circuit board attached and is a bit simpler. Would the BS2p24/40 Demo Board support the regular BS2 and would i be able to use it for my robots? I would realy just like somthing with a place for a BS2, a soderless circuit board, and a place for some servers.

Hmm. "Motherboard", "servers", it's beginning to sound like either I'm not understanding you, or you're not understanding me.

What are you calling a "server"? In my work, that's usually an IBM-PC of some description (486, Pentium 1,2,3,4,5, etc) or a Sun workstation, or something like that. Are you looking for a Web Server portal, perhaps?

I'm guessing you're referring to servo's when you mention server. The Board of Education is a popular board that has multiple servo connections www.parallax.com/detail.asp?product_id=28150 and costs $65.

If costs is more important, then the Super Carrier board is a good alternative at $20 and you can add servo connections on the solderless breadboard. You can get a small solderless breadboard here www.parallax.com/detail.asp?product_id=700-00012 for $4.95. and get one of these cables/headers for each servo you want to add for $1.29 each www.parallax.com/detail.asp?product_id=805-00001,451-00303

I have a few generic 3 1/8" by 1 7/8" boards that I merely soldered a 24 DIP socket and two 12pin headers along side. That pretty much omits the programing. There is space to a a five volt regulator and a reset button. One could easily put in plugs for 4 servos too. Then you could wire with jumpers.

If I want to program, I have built a DB-9 with the capacitors on the Atn Line that directly connects to the 4 pins of one of the 12 pin headers. But you could just as easily not provide access to those 4 pins [noparse][[/noparse]Tx, Rx, Atn, and Grn] and use an 8 pin header on that side.

A power on Led is also helpful.

I like my bs2 oem plugged straight into a breadboard or two glued to some backing board
