We've all seen the Bluetooth modules for cheap on ebay/store fronts..etc..
(specifically the HC-5 & HC-06 modules)
HC-05: Master/Slave http://imall.iteadstudio.com/im120723009.html
HC-06: Slave http://imall.iteadstudio.com/im120723010.html
usually these come either plain-jane, like in the link above..
My question is..
1.) besides having a head on it..for easy connection/breadboard friendly... what does the BASE board provide? * (I understand the pin spacing on the main board is odd/not breadboard friendly..etc)
2.) I see the BASE board has more components on it too? resistors, caps, an led? and either vRegulator or transistor..?.. and maybe a diode?
I guess Im not clear what the base board adds/offers?
leds flashing to show data transfer?
From what I gather.. these BT boards operate at +3.3v logic level.. but I dont see any level shifter on board.. (nor voltage divider)
Can I just solder directly to the base board.. or possibly just EMBED this whole HC-05/6 MAIN board into/onto another PCB?
(ie: design a circuit/pcb that has an area where the whole HC-05/6 board is re-flowed into it during assembly?)
