This project shows a DC-DC buck boost circuit which can produce an output of 3.3V for an input of 2.7V to 4.2V , for example from a Li-on battery. The Circuit uses LTC3440 Buck boost IC which is a fixed frequency boost converter. To get high efficient results, inductor with high...

Single Channel Large current relay board with dual DC-DC converter board is mainly designed for Hobby CNC, Routers, and Plasma cutters. Hobby CNC controller requires multiple DC outputs to drive various things.  This board provides 5V DC and 12V DC 1Amp each. The dual supply helps...

The tiny board designed using A3979 IC from ALLEGRO which is complete micro stepping driver with built in translator. The translator is the key to the easy implementation of the A3979. It allows the simple input of one pulse on the STEP pin to drive the motor one micro step, which can...

4-Channel Relay Board is a simple and convenient way to interface 4 relays for switching application in your project. The project has large Relay which can switch current up to 20Amps. Specifications Input supply 12 VDC @ 360 mA Output four SPDT Relay Relay specification...

This Module has been designed around Nuvoton’s ISD1932 ChipCorder®, the newest single-chip multiple-message record/playback series with dual operating modes (address trigger and direct trigger) and wider operating voltage range from 2.4V to 5.5V. The sampling frequency can be...

PIC16F 28/40-pin Development Board will help you with your prototyping requirement with any of Microchip's 28/40-pin of 16F PIC microcontrollers. Specifications All ports terminating in separate box header connector with 5 VDC source option ICSP connector for programming for...

This is a simple circuit to measure the temperature of any environment and display it on a 16x2 LCD module (C013). This is just an temperature indicator project and not a controller circuit. Circuit works with 7-9V DC. The circuit uses a Microcontroller to read a LM35...
