I am creating a device that uses both an Arduino Diecimila and a La Fonera (a type of wireless router). I have connected them via serial and can control the Arduino over the internet via wi-fi. It's pretty cool ;D
Now I am trying to find the best way to power both of the devices from a single wall wart. I don't want to have two power adapters for a single project box!
Can anyone direct me to the best approach? Here are the details:
- The Arduino requires a 9-12v, 250mA+ adapter.
- The Fonera can be provided power through a 5v input or a 3.3v input. I have already tested and found that the Arduino's 5v and 3.3v outputs cannot support the Fonera's power requirements. According to other Fonera users, the router requires up to 800ma at the 5v input or ~700 ma at the 3.3v input.
- My wall wart provides 650mA at 9v.
Thanks in advance, hope this is understandable! :P
