Connection of unused pins


#1

Hello,

I have been using the WizFi210 module connected with only the power pins (9,32,33,34), ground pins, UART0 pins, GPIO29 and GPIO27 for F/W update.

Is it advisable to connect any other unused pins with either pull-up or pull-down resistors (depending on every specific case) or I can just leave all unused pins unconnected (floating) ?

Thank you for any clarification !

Hi

It is no problem to connect only the power pins, ground pins, UART0 pins, GPIO29 and GPIO27.
But we recommend to use as reference Schematic.
