How to connect 2 vex Iq brains together

That would need code running on both IQ Generation 2 brains and a special cable to connect them, see some details in this topic.

How to connect one or more VIQ brains to each other

Here’s a very simple demo using two IQ2 brains. crossover cable (swap scl/sda) with gnd is needed, disconnect power and the other signals. One sends (well, technically they both send in this demo) the string “Hello” the other is receiving it. [IMG_1759] Here is the C++ code, in practice for reliable communication you need to invent a suitable protocol handling partial reception of data, error checking etc. C++ demo code Python code would be very similar.

12 smart ports that you could connect motors to

Then there’s no room for other sensors. 12 motors spilt across two batteries will also work a little better.
