    Description-

    RageBridge 2 from Equals Zero Designs is a no-frills and robust dual-channel DC motor controller for robotic and vehicular drivetrain applications. It can supply 40 amps per side continuously and up to 90A in bursts dependent on cooling conditions. An ultra-wide (8 to 40 volts) input range maximizes versatility and allows it to be used in many different systems. It can operate as two independent motor control channels, or be combined into a single-channel controller for driving larger motors. It can take analog, R/C radio, and TTL serial inputs. A large and fully isolated heat sink base allows you to attach it to a metal chassis for even better thermal performance. RageBridge 2 is truly a controller you will not “grow out of”!

    RageBridge 2 is a dual H-bridge allowing control of up to two DC brush motors independently, integrated onto a single board. The switching topology of RageBridge 2 is known as “synchronous rectification“. In this method, the motor is always being alternately powered and then braked. While it may sound unnecessarily complicated, it significantly decreases heat dissipation in both motor and power MOSFETs because current is never just being burnt off as heat for a portion of the switching cycle. The result is a controller that can handle more power in a smaller package.

    Additionally, the bidirectional current flow means the battery supply gets recharged when the motor is undergoing braking, with energy supplied from the kinetic energy of the moving drivetrain or actuator. This translates to an increase in run time of a few percent in most cases.

    Don't miss out on this out-Rage-ously powerful gadget!
