Motoron Motor Controllers
The Motoron motor controllers make it easy to control DC motors through an I²C or UART serial interface. Each module can independently control up to two or three bidirectional motors, and multiple controllers can be stacked or chained together for projects that need to control even more motors.
The tables below list the members of the Motoron family and show the key differences among them. Each type is available in several versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with connectors soldered in, as a kit with connectors included but not soldered in, or (for Arduino and Raspberry Pi expansions) as a standalone board without connectors.
