I recently bought an RF24L01 radio module to connect it with my arduino esplora.
Sadly the Esplora has the 5v power only, and the module requires no more than 3.3v.
How can I convert these 3.3v into ampere to apply the Ohm's theory?
I also have this chip
Is this any useful? If so, how do I have to connect it to the Esplora and the Radio module?
