This module is an isolated full-duplex differential line driver and receiver for TIA/EIA RS485/RS422 applications. The module is ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical barrier of the...

This is a versatile tiny module that provides 10V/500mA from 90V DC input. It is a high voltage input DC-DC buck converter, based on LM5017 IC, which is a 100-V, 600-mA synchronous step-down regulator with integrated high side and low side MOSFETs. The constant on-time (COT) control...

Arduino Nano RS485 shield will help you to transmit and receive serial data using the twisted pair RS485 network. The module provides half-duplex communication. LED D1 indicates receive data, D2 Transmit LED, J1 jumper is optional and not in use in this application. DI/RE connected to...

I designed an audio power amplifier board based around the TPA3116D2. I choose the highest possible oscillator frequency of 1200khz. Many Chinese designs feature no output LC filter which may result in power losses and lower efficiency. Because of that, I choose higher grade...

This small constant current LED driver Nano shield has been designed using CAT4104 IC from ON semiconductor. Its 4 channel LED driver. The board has provision to mount 20 SMD 1206 LEDs. The LED can be RED, GREEN, BLUE and WHITE. Reduce the number of LED to 12 if White LEDs are used,...

The project published here is based on SSM2019 IC which is a latest-generation Pro audio preamplifier. A female XLR connector is provided to connect differential Micro-phone. Circuit also provides Phantom power input, combining SSM preamplifier design expertise with advanced...

The project published here is a high-voltage adjustable regulator with an output 48 V DC from an input supply of 125V DC. The circuit is capable to drive load current up to 500mA. This regulator circuit designed for use in high-voltage applications where standard bipolar regulators...

Project Goal: To measure the atmospheric pressure using one of the best modules i,e BMP280 Pressure sensor module. Components Used in the Project: Arduino Uno BMP280 Connecting Wires LCD 16 X2 BMP280 Pressure Sensor Module The BMP280 sensor module operates with...
