This is a 16-channel servo driver that can drive 16 x RC servos over I2C interface. The project is built using PCA9685 chip, a 16-channel PWM generator that can drive 16-channel servos simultaneously. The board can be connected to Arduino or another microcontroller. Driving robots, and animatronics puppets is easy with this board. The board works with 5VDC and a separate power supply connector is provided to power the RC servo with 6VDC. 6 x address Solder jumper is provided to set the board address, and this helps users to wire up 62 board on a single I2C line and drive up to 992 servos. The board also can be used for other applications that require 16-channel PWM signals. The frequency can be adjusted between 24 Hz to 1526 Hz and the duty cycle ranges from 0 to 100%.

It is important to use a high current power supply that should be able to power the total load of 16 servos and use a C4 = 1000uF/10V capacitor. You can also download the Arduino code to test the board. The test is done with Arduino UNO. The following Arduino pins are used to perform the test, refer to the connection diagram for the connection between Arduino Uno and the PWM board.
This is a low-cost position control closed-loop analog-servo using brushed DC motor and potentiometer as feedback. This product provides all necessary active functions for a closed-loop servo system using a Brushed DC Motor and potentiometer mounted on the output shaft of the DC Motor with Gear. The module is ideally suited for almost any servo positioning application. Can be used in applications such as side mirror movement control for cars, car head lamp beam control, animatronics, robotics, etc.
This is a power-saving pulse-width modulator (PWM) controller for solenoids with an internal supply regulator. The board is based on the DRV110 IC which is a PWM current controller which is specifically designed for solenoid and relay applications. The project regulates the current with a well-controlled waveform to reduce power dissipation on the load. The solenoid current is ramped up fast to ensure the opening of the valve or relay. After initial ramping, the solenoid current is kept at a peak value to ensure correct operation, after which the current is reduced to a lower hold level to avoid thermal problems and reduce power dissipation.
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. Servo movement can be mimicked using the onboard potentiometer. Servo movement data is stored onboard the EEPROM memory chip. The project is Arduino compatible and can be modified to work as a data logger and other applications that require EEPROM and SD Card data logs.
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 for most AC servo drivers. The project provides a jitter-free high-frequency pulse, direction, and enable signal. The output frequency can be configured up to 12 MHz since the project is Arduino-compatible. All outputs are open collector types (5V). 2 x tactile switches are provided to set the direction and enable. An onboard trimmer potentiometer is provided to adjust the step frequency.
The project presented here is a low-cost position control closed-loop analog-servo using brushed DC motor and potentiometer as feedback.
