@mtoko: So glad you're happy with it and thanks for ordering the second kit.
I agree a relay modulo would be nice, though for low voltage (up to 18V) DC loads the motor driver modulo can be used. Curious what sort of voltage and current you would want the relay to be rated for? Relays rated for higher voltage/current are of course larger and more expensive.
A tutorial on modulo communication sounds good. What sort of things are you looking for? Practical info on how to use it? Pinouts? Protocol details?
An international distributor/retailer would be great, and we're working on getting those deals in place. One thing that would help a lot is if people would contact those retailers and ask them to carry it. Having customers ask for it probably carries more weight than me just cold calling them.
Thanks a lot!
