Hello,

i recently started working with the arduino pro mini and the nrf24L01+ (and more or less with hardware at all).
The board has 3 ground pins. While wiring up with jumper wires i used one for the nrf chip, one for the battery and one for the voltage regulator.
My problem is that there now is no ground pin left for the temperature sensor. What are my options here when i do not want to solder? Can i use the BLK pin as ground? Are there some kind of Y shaped jumper wires? Or is there another solution?

Have a nice sunday
Michael
