You read it right. Not even 3 weeks after the EV3 has started shipping, Mindsensors are working on getting ready to release another cool gadget for it. This time it’s an EV3 Sensor adapter for NXT or Arduino. It seems to allow you to connect the new EV3 sensors to your NXT or Arduino. I don’t have any if the specs yet but one of them should be on its way to me very soon, as well as some preliminary docs.
What I do know is that they will retail for about $10 and should be available around mid-September.
