Features :
The OpenRB-150 is a new open-source Arduino compatible embedded controller.
The controller has the same pinout and form factor as the Arduino MKR, and supports programming using the Arduino IDE.
It also features 4 dedicated DYNAMIXEL ports, and supports the DYNAMIXEL Wizard 2.0 for easy use and maintenance of DYNAMIXEL.

How to Supply Power (3 Methods)
Power can be supplied to the OpenRB-150 in three ways depending on the voltage and serial communication type of DYNAMIXEL.
1. 5V TTL DYNAMIXEL

2. 12V TTL DYNAMIXEL 

3. 12V RS-485 DYNAMIXEL

Compatible DYNAMIXEL : The OpenRB-150 is compatible with all DYNAMIXEL models.However, additional equipment is required for use with the following types of DYNAMIXEL.
1. RS-485  :  The DYNAMIXEL Communication Bridge is required to convert signals. 
2. 24V  :  A separate power supply is required.
3. DYNAMIXEL-AX and MX Series (Molex connectors)
A Molex-JST convertible cable is required.
Caution
The Arduino MKR board is not included in the package.
When supplying power, please check the jumper settings. (USB C Type, VIN, Terminal VIN)
Please do not charge the battery when it is connected to the controller.
Please check the power input terminal before connecting it to the controller.
