Компонент Adafruit DC+Stepper Motor HAT
Воплотите свои роботизированные мечты в реальность с новой шляпой с шаговым двигателем постоянного тока + от Adafruit. Это дополнение Raspberry Pi идеально подходит для любого проекта motion, поскольку оно может приводить в действие до 4 двигателей постоянного тока или 2 шаговых двигателей с полным регулированием скорости ШИМ. Поскольку Raspberry Pi не имеет большого количества ШИМ-контактов, мы используем полностью выделенный чип ШИМ-драйвера на борту как для управления направлением, так и скоростью двигателя. Этот чип управляет всеми функциями двигателя и скоростью через I2C. Для управления несколькими двигателями требуется только два контакта (SDA и SCL), и поскольку это I2C, вы также можете подключить любые другие устройства I2C или головные уборы к тем же контактам. На самом деле, вы даже можете сложить несколько головок двигателя, до 32 штук, для управления до 64 шаговыми двигателями или 128 двигателями постоянного тока (или их сочетанием) - просто не забудьте приобрести и припаять к ним штабелирующую головку вместо той, что входит в комплект поставки. Двигатели управляются МОП-транзисторными драйверами TB6612 с Мощность тока 1,2 А на канал (вы можете использовать пиковый ток до 3 А в течение приблизительно 20 мс за раз), что значительно лучше по сравнению с драйверами L293D, а также имеются встроенные обратные диоды.
