REOBoard stands for Recreational, Educational, Original Board. It is a BlueTooth Low Energy capable board aimed at leisure or educational robotics. It can receive messages from a smartphone (iOS or Android) and drive up to 6 servos and 4 DC motors simultaneously.
Also provided as a convenience for REOBoard buyers, this is a small servomotor. Although it is made with plastic gears, it's quite robust and largely sufficient, for example, to drive a small robot steering component.
