Good evening,
I'm looking into how to connect an xBee directly to the Arduino without a shield. I know I can directly go 3.3v of the arduino to the xBee, and the TX of the xBee to the RX of the Arduino as the arduino should accept 3.3V logic? But what is the best way for me to convert the TX 5v of the arduino to 3.3v?
I've seen it done with resistors and diodes, but I've also seen information about how they aren't the best solution. I do have some 6N138 but they invert logic and I'm not looking to use softwareSerial...
Is there any smaller chip I could use to help me achieve what I'm after? I don't want to buy an modules as I'm limited on space so something I can solder to my PCB...
Thanks
