I feel like this could go really well with this:

Awesome.  A network of 4 and external network connection would be interesting. :)

Sparkfun has it available for pre order with available date of later this week.

I'm only on the fence about the switch because $99 seems a bit pricey, but I totally dig the utility of having a *-duino-sized 4-port switch inside my rover.

Ha! I just bought some 3.6-es for spares. Now I need to upgrade :-)

Also: Why buy from SparkFun? PJRC has a store all of their own, and I imagine that they make more money back if you buy directly from them. It's a two-man enterprise with open source designs and significant investment in the software support side (SIGNIFICANT!) so I like to give Paul and the folks all the direct support I can.

Also: already in stock!

Oh, no! The serial port pins have moved around a lot. The 4.1 is not a drop-in replacement for 3.6 on my robot control board :-(

That board is a 4-layer surface-mount monster with dual-rail buck converters, high-current power switch, various sensor and motor drivers, a two-way video switch (!) and more. Cost a fair bit to develop, so not likely to just re-route and re-spin it.

Than again, the 600 MHz? If I really needed performance, I'd use a Raspberry Pi 4 or a Jetson of some sort (the Xavier Nano is coming out now, too.) Maybe the 3.6 is the epitome of "wire wiggler" microcontrollers, and anything fancier will just be a two-board solution.

Sincerely,

Jon Watte
