I have been using a SparkFun BlueSMiRF module with a MSP430G2553 chip on a breadboard. I want to create a custom circuit to have everything on one board.
Here are a few questions before I go about this:
- Can I connect the Tx and Rx lines from the RN42 directly to the MSP430 without the level shifting circuits since the MSP430 runs on 3.3v as well?
- Can I leave the RTS and CTS connections on the RN42 floating since I will only be using 9600 bps?
- I have a Vcc of 3.3V, so I will be removing the voltage regulator circuit at the top left. (Not really a question, but if I'm doing something wrong here, hopefully someone will point it out).
Thanks for reading!
