L293D 馬達驅動擴展板/Motor Control Shield for Arduino

L293D 馬達驅動擴展板 是一款常用的直流電機驅動模組，採用293D晶片小電流直流電機驅動晶片。管腳被做成了Arduino相容的，也方便了愛好者快速的基於Arduino的開發。

L293D 馬達驅動擴展板 特色

• 2個5V伺服電機(舵機)埠 聯接到Arduino的高解析高精度的計時器-無抖動！
• 多達4個雙向直流電機及4路PWM調速（大約0.5%的解析度）
• 多達2個步進電機正反轉控制，單/雙步控制，交錯或微步及旋轉角度控制。
• 4路H-橋：L293D 晶片每路橋提供.0.6A（峰值1.2A）電流並且帶有熱斷電保護，4.5V to 36V。
• 下拉電阻保證在上電時電機保持停止狀態。
• 大終端接線端子使接線更容易（10 – 22AWG）和電源。
• 帶有Arduino重定按鈕。
• 2個大終端外部電源接線端子 保證邏輯和電機驅動電源分離。
• 相容Mega, Diecimila, & Duemilanove。
• 下載方便使用的Arduino函式庫快速進行專案開發

適用範圍：Arduino初學者，Arduino實驗器材平臺，Arduino互動電子，Arduino機器人等。
特點：功能多，操作方便，有強大的驅動庫支援及功能更新。
缺點：I/O佔用較多在同時驅動四路電機的情況下（相對Arduino I/O少的版本而言），小功率。

L293D 馬達驅動擴展板 可驅動4路直流馬達或者2路步進馬達的同時還能驅動2路伺服馬達,支援最新Arduino UNO, Arduino Mega 2560

您可以這樣搭配：驅動四路直流電機和兩路舵機驅動兩路直流電機和一路步進電機和兩路舵機驅動兩路步進電機和兩路舵機

L293D Motor Driver Shield Expansion Board

• This motor driver shield is based on L293D motor driver chip which is designed to provide bidirectional drive currents of up to 1.2 A each bridge with thermal shutdown protection at voltages from 4.5 V to 36 V.It is designed to drive up to 4 bidirectional DC motors with individual 8-bit speed selection.

  It can also drive 2 stepper motors (unipolar or bipolar), single coil or double coil, interleaved or micro-stepping. It contains 4 H-bridges which provide up to 0.6 A per bridge (1.2 A peak).

  This shield has pull down resistors to keep the motors disabled during power up.

  It also features a 2-pin terminal block to ensure separate logic and motor external power supplies.

  This expansion board is compatible with Arduinos Mega, Diecimila, and Duemilanove.

  This motor driver shield is capable of driving:

  • Four DC motors and two servos
  • Two DC motors, stepper motor, and two-way servo
  • Two stepper motors and servos

  Specifications

  • L293D motor driver chip
  • Four H-bridges
  • Terminal blocks for power supply and DC motors
  • Reset button
  • Big terminal block connectors (10-22 AWG)
  • PCB Size: 69 mm x 53 mm
