Part Number: DS90UB934-Q1

Hi Team,

Could you please tell me how we should treat the unused GPIO pins on 934 ?

Q1) Can we keep them floating ?

Q2) If user wants to pull down, can they directly connect to GND ?

Best Regards,

Hello,
You can leave the GPIO's open/floating if they are not used.

Hi Palaniappan-san,

Thank you for the information.

If customer wants to pull down to low, can they directly connect these pins to GND ?

Best Regards,

Hello,
Sorry for the delay in response. If they want they can pull down to low, but better to use a 10K ohm resistor.
