2 Motor + 16 Servo Motor Drive Module

Introduction

2 Motor + 16 Servo Drive Shield is compatible with Arduino UNO and ESPUNO of a servo motor and drive module. Plug-in modules stacked circuit board design, you can directly access the Arduino UNO or ESPDUINO board.

The product can simultaneously control two -way DC motor ( 4.5 of 5 ~ 36V ) and 16 -way steering gear ( 5 ~ 18V ) , suitable for mobile robot equipped with a robot arm driving control.

Modules STMicroelectronics produced the outstanding high-power motor drive dedicated full-bridge chip L293DD , can directly drive 2 -way DC motors or 1 channel stepper motor drive current can be up to 1.2A . Schematic layout reasonable, SMD package, very easy to install.

Module IIC interface control 16 road servo.

Module Arduino UNO and ESPDUINO the IO port as a control port, so that only the control panel occupies D6 , D7 , D11 , D12 (for ESPDUINO , compared with D12 , D13 , D3 , D1 ) four ports, respectively, as PWMB (motor B speed ), DIRB (motor B direction), PWMA (motor A speed), of DIRA (motor A direction) function.

Module using humanized design, using the power button switch, the user can easily switch.

This module can be used to control intelligent robot using Bluetooth (reserved line interface) or wifi control, reference control UNO source in the Annex.
