Hello!
I've just assembled Freeduino board and it works perfectly.
I have usb GPS which I want to use with my arduino.
The chip inside the receiver has only 4 wires - +/GND/RX/TX which is very convenient. Unfortunately I don't know the name of the chip. What I do know that it uses 3.3.v.
I can't connect it to the board as it draws more than 40ma.
So I think I'm going to use LD1117 for power, but what about serial lines?
Do I have to use something? If so, examples would be very appreciated.
Same thing you need to do with xbee,s .
you need to use a voltage divider from 2 resistors for the Rx on the gps , but you don`t have to do anything about the tx from the gps , 3.3v is still o.k
Thank you for replies! peter247, how this divider would look like? What would be the resistors values? Lefty, I'm writing from Poland, so it would take to long to get that converter and too expensive (shipping).
