Trying to understand the schematic, and make the Rn41 work with the Uno.
In the schematic I've attached from Sparkfun:
The part I've highlighted in BL: Could that be replaced with the Logic Level Converter from SparkFun (http://www.sparkfun.com/products/8745)
The part highlighted in RD: Is that just a 3.3 volt power supply? So the Uno has a 3.3 v pin, I could use, correct?
This is starting to all look pretty easy.
...what is the part I've highlight in GR?
And lastly, There are 4 pins being connected, but I thought I'd just need Rx and Tx for a general purpose 'serial pipeline'? Do I need rts & cts?
