This is a compact, low-profile, and high-performance DC motor driver that provides easy control of a DC motor using a joystick. This small-size board can drive small to medium-sized brushed DC motors with up to 2.5A continuous and 6A peak currents. It is an Arduino-compatible project...

This is a pulse generator for a stepper motor driver using a joystick. It is a board that contains an Arduino-compatible microcontroller and circuitry for controlling up to 2-channel (2-axis) stepper motors. The board has multiple options to develop stepper motor-related control...

The board presented here is multipurpose hardware which includes the ESP32-Wroom module, 3.3V regulator, 5V relay, Power LED, Relay LED, and connector to program the ESP-32 Module. The project requires 5VDC and consumes 60mA current when the relay is ON. The project can be used in IoT...

The module presented here is a sensor signal conditioner based on ZSC31010 CMOS integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM programming. When mated to a resistive bridge sensor, it will digitally calibrate offset and gain with...

This PT2315E IC-based audio processor is designed for versatile applications and includes master volume control with low-frequency loudness compensation, speaker output attenuator, and tone control. It is a good solution for home audio signal processing. Due to the high-reliability...

This is an RC servo controller board that allows users to record RC servo motor movement and playback it back with precision. There is an onboard potentiometer to control the RC servo up to 180 degrees. It allows you to record the movement of one servo, a few seconds in duration....

The circuit shown here is a high-side voltage-to-current (V-I) converter. It translates an input voltage of 0 V to 2 V to an output current of 0 mA to 100 mA. The low offset voltage and offset drift of the OPA2333 facilitate excellent DC accuracy for the circuit. The project...

This 4-Channel current sense amplifier is designed for cost-optimized applications. This is a current-sense amplifier (also called a current-shunt monitor) that senses the voltage drop across current-sense resistors at common-mode voltages from –0.2 V to +26 V, independent of the...
