It \u003cstrong\u003eincludes a set of two M2.5 standoffs (11 mm length), screws, and nuts\u003c\/strong\u003e that can be used to secure the board at the proper height for the GPIO connector.\u003c\/p\u003e \u003chr\u003e \u003cp\u003eThe Motoron M3H550 add-on board makes it easy to control up to three bidirectional, brushed DC motors with a compatible Raspberry Pi (Model B+ or newer). It supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor.\u003c\/p\u003e \u003cp\u003eThe M3H550 is designed to stack on top of a Raspberry Pi (Model B+ or newer), similar to a HAT (Hardware Attached on Top), and multiple Motoron controllers can be stacked on top of each other, allowing independent control of many motors. Unlike most Pololu motor drivers and motor driver expansion boards for Raspberry Pi, the Motoron does not require any PWM outputs on your Raspberry Pi. Instead, the Raspberry Pi communicates with the Motoron using I²C, so only two GPIO pins are needed regardless of how many Motorons you connect.\u003c\/p\u003e \u003ch2\u003eConnection
