<![CDATA[SKU:U087 with Raspberry Pi 4]]>Hello,
I wish to buy "Voltmeter Unit" SKU:U087 to use on Raspberry Pi 4 I2C bus.
I don't understand the features about 5VDC and 3.3VDC.

  • Can you confirm the diagram on how to connect the grove cable on GPIO Pins ? Do you agree with my picture ?

Best regards.
