I'd like to power an Arduino Nano with a wireless battery and charger , the kind used with samsung wireless chargers , i am looking to shop for this parts
- where can i buy the battery that will work with the wireless plate or both.
2.how do i power the nano ,what pin what voltage?
huge thanks ,
I believe you are trying to duplicate the QI charging system used in cell phones. Unfortunately it is not as simple as just getting a coil and a battery.
The wireless system provides AC voltage and current at the receiving coil. This must be rectified and made to charge a battery. I don't know about the phone chargers but my toothbrush runs at 20kHZ.
You will need:
- Receiving coil
- circuit to convert to DC voltage
- circuit to regulate the voltage from 2)
- battery or load.
The voltage from the receiving coil will vary a lot. THis is due to variations in coupling from the source coil.
To continue, you might want to find a wireless cellphone charging adapter. I've seen them as replacements for the back of some older phones.
Or you could look at things like this ZENS Qi-enabled portable battery makes charging truly wireless, almost
