The Module is based on The MCP2200, which is a USB-to-UART serial converter which enables USB connectivity in application that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256-bytes of integrated user...

The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes,...

Tiny stereo audio amplifier board has been designed around SMD TDA7266D IC from ST. The TDA7266D is a dual bridge amplifier specially designed for Portable Audio, LCD TV/Monitor, PC Motherboard, and TV applications. This circuit provides high quality audio output of 3W approx. on each...

Introduction This power supply appeared in the summer issue of Elektor 2000 without a PCB layout. So, I decided to build a PCB using Cadsoft EAGLE Lite edition following the Elektor’s schematic and introducing some changes. The power supply uses through-hole parts which are...

Dual Motor L298 H-Bridge Control project can control two DC motors connected to it.  The circuit is designed around the popular dual H-Bridge L298 from ST. This board can be configured to drive a single motor with high current rating also. This can be achieved with the help of...

Programmable relays find use in numerous automation applications such as automatic street light control, watering and pump control, HVAC, home automation, power plants automation in industries, etc. This article describes how to build a fully functional, one-channel programmable relay...

This Half-bridge driver based on IR2104 gate driver IC and N channel Dpak  MOSFET  , The IR2104 is a  high voltage, high speed power MOSFET driver with independent high and low side referenced output channels. HVIC and latch immune CMOS technologies enable ruggedized monolithic...

Current Sensing Switch is designed to operate a Relay Contact when there is a DC current through the sense resistor exceeds the set point, Set point adjustable from 1A to 3Amp using on board potentiometer.  This circuit can offer over current protection to your...
