Motoron M1U550 Single Serial Motor Controller (Header Pins Soldered)

Overview

The Motoron M1T550 and M1U550 暧暧视频免费观看 make it easy to control a single bidirectional, brushed DC motor using an I²C or TTL serial (UART) interface, respectively. These compact (0.6″ × 0.6″) boards support motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.8 A. Multiple Motoron 暧暧视频免费观看 can be configured to work on a single I²C or serial bus, allowing independent control of many motors. Unlike most of our motor drivers, the Motoron does not require any PWM outputs or timers on your microcontroller. Instead, only a single I²C or UART interface is needed regardless of how many Motorons you connect.

These Motoron 暧暧视频免费观看 are available in several versions with different combinations of communication interfaces and connector options:

• M1T550 (I²C):
  • headers soldered
  • headers included but not soldered in
• M1U550 (TTL serial):
  • headers soldered
  • headers included but not soldered in

For dual-channel alternatives, consider the Motoron M2T550 and M2U550.

The Motoron family

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 被猛男狂cao的小男生: they can be purchased as an assembled product with 被猛男狂cao的小男生 soldered in, as a kit with 被猛男狂cao的小男生 included but not soldered in, or (for Arduino and Raspberry Pi expansions) as a standalone board without 被猛男狂cao的小男生.
