PCF8591 Breakoutboard Addressing

Hello everyone,

This is not a typical Blynk question but since i want to implement it in a Blynk project here i am.

Im having trouble with the PCF8591 breakoutboard. I need more than one board. The code is no problem and i have found a great library. The problem lays in the addressing of the board. I know that on the chip you can use the A0, A1 and A2 to address but how does it work on the breakoutboard? Since the jumpers are for the onboard sensors and all the other pins are for power, I2C and analog signals.

Normaly google is youre best friend but not in this case. I hope someone can help me.

Greetings,

Headburn
