Description

This shield is designed for the NodeMCU Amica variant. It has L293D motor driver and breakout the GPIO to headers for easy connection with various sensor modules. This shield can drive two brushed motor for the motion of start, stop, brake, steering, direction and speed control. The shield also extends the GPIO of NodeMCU to header pins in SVG configuration (compatible with servo), also the UART, SPI, Power and GND pins. There are options to power the board separately or with single power source. The board also comes with a power LED indicator and latching push button as power on/off switch.

This shield is very convenient and cheap to build or DIY a WiFi RC smart car or any type of robotics or even UAV platform.

Features:

  • On Board motor drive L293D IC, support two channels of DC motors via screw terminals
  • Motor power supply (VM): 4.5V ~ 36VDC, can be a separate power supply
  • Control power (VIN): 4.5V ~ 9V (10V MAX), can be powered separately
    • Module provides short-circuit header pin (short VM and VIN), you can easily use one power (which must be 4.5V ~ 9V) simultaneously drive and control the motor.
  • Compatible with NodeMCU Amica but not LoLin variant
  • Logic Operating current: ≤60mA (Vi = L), ≤22mA (Vi = H);
  • Motor Driver Output Current Per Channel: ≤1.2A (Based on L293D)
  • Maximum power dissipation: 4Watt (T = 90 ℃)
  • Control signal input level:
    • High: 2.3V≤VIH≤VIN
    • Low: -0.3V≤VIL≤1.5V
  • Working temperature: -25 ℃ ~ + 125 ℃
  • Drive Type: Dual high-power H-bridge driver (L293D)
  • With NodeMCU based on ESP8266, it supports:
    • Support wireless 802.11 b / g / n standards
    • Support STA / AP / STA + AP three operating modes
    • Built-in TCP / IP protocol stack to support multiple TCP Client connection (5 MAX)
    • D0 ~ D8, SD1 ~ SD3: used as GPIO, PWM, IIC, etc., port driver capability 15mA
    • AD0: 1 Road ADC
    • Current: continuous transmission: ≈70mA (200mA MAX), Standby: <200uA
    • Transfer rate: 110-460800bps
    • Support UART / GPIO data communication interface
    • Remote firmware upgrade (OTA)
    • Smart Link supports intelligent networking capabilities
    • It can work at many modes, such as: AP mode and STA mode
  • Motor Control Pins:
    • D1(NodeMCU) = GPIO5(ESP8266) = PWM of Motor A
    • D3(NodeMCU) = GPIO0(ESP8266) = DIR of Motor A
    • D2(NodeMCU) = GPIO4(ESP8266) = PWM of Motor B
    • D4(NodeMCU) = GPIO2(ESP8266) = DIR of Motor B
