This is a direct drive 4WD base Programmable robot kit that uses Nexus mecanum wheels and hubs. This robot platform is meant for indoor robotics. It can vector in any direction. It makes a great Autonomous Robot.
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A.
