PC817 module with 8 optocouplers

A set of two cameras with a Sony IMX219 sensor, allows you to rotate the camera and control the tilt angle. Works with Jetson Nano and Xavier NX. The camera is equipped with an 8MP matrix. ArduCAM B0191PT

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with connectors for assembly. Pololu 5052

The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. COM-13705

Non-invasive AC Current Sensor, 20A, YHDC, RoHS

TB6612FNG dual DC motor controller module. It can be used as a stepper motor driver or solenoid driver. Adafruit 2448
