What is CH340? CH340 is a TTL (serial) to USB converter and vice versa. This chip has been used in some boards such as Arduino Uno CH340G, ESP8266, etc. The boards using the CH340 chip, don’t need a programmer in order to access the processor or to program them.But there is a downside. An extra driver must be installed before starting to work with boards having this IC. In this tutorial, you will learn how to install CH340 driver.You can apply this guide to all Windows versions, including Windows 11,...

L298N DC Motor Driver Feature L298N module is used to drive DC motors with a current of less than 2 amps. This module is easy to use. It contains convenient filter circuit and have access to inputs and outputs via pin headers and terminals. The L298N is a dual full-bridge motor driver that allows two DC motors to be connected simultaneously. Note The L298N motor controller follows the H-bridge configuration, so it can be used to drive stepper motors too. This driver needs a logic voltage supply to drive t...

MX1508 Motor Driver Module Features The MX1508 driver is one of the cheapest drivers for running DC motors with a maximum current of 2 amps. Small dimensions and simple setup are the positive features of this module. The MX1508 is a dual full-bridge motor driver that allows two DC motors to be connected simultaneously. Note The MX1508 motor controller follows the H-bridge configuration, which is handy to drive a stepper motors.This driver has a temperature protection circuit that disables the d...
