AM-100 Analog to Digital I2C Converter PCF8591 with cable

This small device allows you to send in four possible analog signals varying from voltage to be adjusted and converted into digital signal using I2C pinouts for any microcontroller. Use the potentiometer to adjust the desired output digital signal voltage you want for your microcontroller. Works great with raspberry pi, or other voltage sensitive devices. Jumpers will create a short that uses the photo resistor for testing with your microcontroller, please remove jumpers when using analog pins and adjusting voltage with voltmeter. Please keep the jumper in place If you are connecting to a raspberry pi or 3.3v pinout sensitive device.
