Hiwonder LX-15D Intelligent Serial Bus Servo with RGB Indicator for Displaying Robot Status

This motor have sensibility to higher voltage, no protection if you have to high voltage. For beginner is good, to understand the ID of each motor with TTL network between motors. But no RS-485 solution. You don't have bigger motor with 100 or 200 kg/cm for torque. In reality you can't connect many motor on the same network, because you have limitation of Amp! You can find at Robotis solution to add power when you should use many big motor. This motor are good for beginner, but the resolution of encoder is limited and you don't have PID processus in each motor(Robotis have). It's better of PWM motor, but under Robotis motor, but the price is lower! The Hiwonder drive controler have time motion for each movement, you can simulate smoth movement. If you use this robot with ROS, you can have similar movement of ABB MoveL...

Haven't put them to use yet, still studying how to set the address. xArm makes a great third hand for soldering, assembly of other projects, as well as learning something about robotics.
Could be improved a lot with the capability to handle movement restrictions without damaging the servo, perhaps an overcurrent cutoff, max force control? Other devices are starting to have this capability.
