Agreed - RS232 is not recommended over 15m - it’s much better to use RS422 or RS485 because they use balanced (differential) data lines. (Each TX/RX line has a positive and negative signal, so the net magnetic flux produced is ideally zero. This means they not only don’t produce much EM noise, they’re also more immune to receiving noise)

I’d be interested in seeing what multiple RS232 lines in conduits over long distances looks like - I suspect there’d be a fair bit of noise transmitted.

There’s an mbed 3pi extension board available here, and complete package here. The mbed is great for high-level things like wireless communication, AI, etc, while the ATMega on the 3pi does low-level tasks - motor control, IR sensor/voltage readings.

Also, your comment count appears to be off. Title says 33 (which is correct), comments heading says 36.
Furthermore, last time I commented Firefox tried to make me download a .json file.

“We’re SparkFun advertising started - and where it will go in the future."
Should that not read "Where ..” ?
