BMS 3S 25A modules are widely preferred, especially for Li-ion battery conversions in cordless drills. The most important advantages of these modules are their cell balancing, overcurrent, overcharge, overdischarge, and..
STM32F103, STM32F303, ATmega32, ATmega328p Amplifier control project is a control module for your audio amplifier. It supports various I²C/SPI controlled sound processors and FM tuners. All source codes and PCB..
The advantages of lithium batteries are many, first of all, high power, low weight and no “memory effect”. Also, a lithium battery has three times the voltage of a nickel-cadmium..
The combination lock circuit displays the information and settings entered from the keypad built on the PIC18F4620 microcontroller on the LCD screen. All user password information settings are kept in..
The control card made for the transformer winding machine can control the winding from 0 to 99.999 turns with 5 steps. You can use common cathode or common anode Led..
Built on stereo tone control circuit TL072, LM358 Opams PCB dimensions are small 56x68mm. The supply voltage of the tone control circuit is unipolar. A virtual ground is created with..
The subwoofer filter, or low-pass filter, is designed to suppress high frequencies that shouldn’t be fed into the audio amplifier’s input and then into the low-frequency head (woofer, subwoofer). The..
A 2X16 LCD screen is used to display the data based on the weekly timer circuit PIC16F628A microcontroller and the DS1302 real time clock IC. There are different software for..
PT2240, PT2262, HT6P20B RF Transceiver ICs were cloned as software and application circuits were made with microcontroller. Clone circuits may be higher in cost, but it is a very good..
The high-power control circuit motor reversing DC motor speed controller circuit features soft start, relay switching of motor direction, and PWM speed control. I have shared the circuit before. There..
