L293D WiFi Motor Drive Expansion Board Shield Module for NodeMCU CP2102
Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power to the motor and the control board
Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) while completing motor drive and control

Screw Terminal Expansion Adapter Board for the Arduino Nano V3.0 AVR
Use this dock to add extra connections to your Nano! It uses screw terminals so that you can be sure the connection is strong, and also use thicker/stranded wires.
This dock must be soldered together and a Nano is NOT sold with this item and is only pictured for illustrative purposes.
Package Contents:1 Nano Dock.

L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper fit Arduino Electric Projects, Smart Car Robot
Dual-channel H-bridge driver working mode creates higher working efficiency,L298N as main chip, Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors.
To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage.
