speakup board voltages

What is the residual or normal voltage on the output pins of the Speakup board when assigned LOW? I am recording 2.2+ volts when toggling the voice command on LOW. I see up to 4.9v, momentarily, when toggled HIGH. Is this appropriate, or should there be less voltage on low and a wider differential?
Thanks,

Hi,

Can you please tell me how do you measure output voltages, do you use GND from the SpeakUp click board as reference?
When it is high, it should be around 3.3V, and when it is low, it should be 0V.

Best regards,
