So I am making a project based around arduino and using the RN-42-HID for bluetooth using HID Profiles. I looked around and find breakout boards like this one for around $38-$45: https://www.sparkfun.com/products/10938. Considering the module itself is only $15 I think I would be better off just making my own breakout board for prototyping.
Secondly I am going to be using a 3.3v arduino pro micro, so the question I have is this. After looking at the schematic on the RN-42 datasheet http://ww1.microchip.com/downloads/en/DeviceDoc/rn-42-ds-v2.32r.pdf it seems like it accounts for 5v input with a LP2985-3.3 linear regulator and uses an SP3232ECA-L RS-232 transceiver to communicate with a PC. Since I am using a 3.3v Arduino I shouldn't need the regulator or the transceiver, right? I could just make a much more affordable breakout board for a 3.3v Arduino without them.
I am new to this level of hardware design so if I made some foolish mistakes then please... be gentle with me ;P.
