@J-M-L

From their own wiki it's powered with 5V and you don't need any resistor at all (unless you want to use the "button interface").

Hum you're right! I've checked so many time mini and pro page that I've registered the 1kohms from the mini wiki...

I'll try that next week, without the resistor...

Thank you
