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,...

FSR-402 Force Sensitive Resistor Features Force-sensitive resistors are simple sensors for detecting weight and force. That’s why they are called Force Sensing Resistor or FSR. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. Put this sensor in the circuit like other resistors to get the output. When no pressure is being applied to the FSR, its resistance will be maximum or infinitive. This is a force se...

BYGH403 1.65A Stepper Motor Features Stepper motors are one of the most widely used motors in robotics and electronics. These motors are actually the same as DC motors that move in discrete steps. They have multiple coils called "phases". By supplying each phase in sequence, the motor will rotate one step (the angle of each step for each motor is specified in its datasheet). with controlling these pulses precisely, you can achieve very precise speed control.Applications:CNC3D printersInkjet printersSca...
