Improve the power of a Board of Education and BoE-Bot

Start with your BoE-Bot - but then ...

Parallax' BoE-Bot is a popular BASIC Stamp® based hobby and educational robot. It comes with excellent courses to get a starting roboteer going. After making the basic robot, some fundamental limitations of the Stamp can make programming more advanced robot behaviors more difficult. By using the BoE's built-in AppMod connector to add our Co-Processor, those limitations dissappear!



We now have a low-cost PCB kit you can buy to make adding our Co-Processor easy. Instead of connecting to the AppMod connector, it fits under either a Board of Education or a Parallax Toddler board. See the Buy-a-Bot page to buy the Co-Processor, Bare PCB, or the complete kit.

Because the BoE-Bot uses a 4 cell supply, be sure to order the Co-Processor with Brownout disabled. Look at the discussion on brownout detection.

Here's the code.

<= Co-Processor AppMod PCB.

That line can be driven low then high at the start of the program and all will be well. Keep that line high during the program to keep from resetting the Co-Processor again.



<= The Sensor Board.
