    Description

    The PCA9685 16-Channel 12-bit PWM/Servo Driver is a powerful I2C-based PWM controller designed for applications that require multiple precise output signals. Built around the PCA9685 chip, this module provides 16 independent PWM channels, each with 12-bit resolution, offering 4096 levels of control for smooth servo positioning or LED dimming. Because it features an onboard 25MHz oscillator, it eliminates the need for continuous signal refreshing from the microcontroller, reducing processing load.

    This module supports Fast-mode Plus I2C communication up to 1MHz, ensuring fast and stable data transfer even in complex systems. It operates from 2.3V to 5.5V and includes 5V-tolerant inputs, making it fully compatible with 3.3V and 5V microcontrollers. Therefore, integration with Arduino, ESP32, STM32, or Raspberry Pi becomes straightforward.

    With adjustable PWM frequency from 24Hz to 1526Hz, it is ideal for servo motors, RGB LEDs, LCD backlights, and signal generation tasks. Featured By RoboticsBD.

    INA125P Instrumentation Amplifier With Precision Voltage Reference

    (0)
    The INA125 is a low-power, high-accuracy instrumentation amplifier with a precision voltage reference. It provides complete bridge excitation and precision differential-input amplification on a single integrated circuit. A single external resistor sets any gain from 4 to 10,000. The INA125 is laser-trimmed for low offset voltage (250µV), low offset drift...
