This is a compact high-power stepper motor driver built for bipolar stepper motors. The driver can be controlled using a serial communication interface (SPI). It combines a flexible ramp generator for automatic target positioning with the industry’s most advanced stepper motor...

The project presented here is an Arduino-compatible motor control board. The board consists of an ATMEGA328 microcontroller, LMD18201 H-Bridge, and 2 x potentiometers. This closed-loop servo system provides position control using a feedback potentiometer mounted on the output shaft of...

This is a Self-oscillating full-bridge project built using the IRS2453 chip. This chip incorporates a high-voltage full-bridge gate driver with a front-end oscillator similar to the industry standard CMOS 555 timer. HVIC and latch-immune CMOS technologies enable ruggedized monolithic...

This is an Arduino-compatible hardware designed for building a low-cost function generator. The project consists of all the required spices to build your own function generator. It includes multiple options such as a potentiometer, rotary encoder, tactile switches, op-amp, and 16x2...

This is a very precise Electronic Load project built using the ultra-Precision, Low-Noise OPAMP MAX44251 from Analog Devices. The project can sink current from a power source. It can be used as test gear for power supplies, chargers, solar panels, batteries, and DC-DC converters. The...

This 6A H-Bridge is designed for the control of DC motors or other inductive loads. The outputs can be pulse width modulated at frequencies up to 20kHz. PWM/DIR control reduces the number of PWM-capable pins needed on the microcontroller side. For load currents above the current...

The 12-Bit programmable contactless encoder project presented here is based on AS5601 chip. This is an easy-to-program magnetic rotary position sensor module with incremental quadrature (A/B) and 12-bit digital outputs. Additionally, the PUSH output indicates fast airgap changes...

A programmable pulse generator is a very useful tool for stepper, BLDC, and AC servo drivers. Various stepper and servo drivers work with step and direction inputs. This project is the right solution to drive such drivers since it can provide a high-frequency output which is important...
