Connecting a Neo to the RoboClaw motor controllers

I am going to guess that because the Neo is 3.3 volts I/O that I will need to buffer the Serial RX and TX when I connect to the RoboClaws RX and TX since its 5 volts based? What would you recommend I use to do the level shift, simple resistors or chips?

Interesting piece of kit (... although expensive), have you thought of connecting/controlling through usb? Having glanced over the datasheet its seems the board provides a virtual serial port (a relativity fast one) which should (hopefully) appear in Linux. Worst case you may need to enable drivers in the kernel.

 

USB only functions if serial port is connected. $$ is due to high current and small size. Working on a mid sized robot and it has large motors

 

A level converter like this should do the trick.
