If anybody need to use BT Serial module in your car, without "base board"
here is a short guide
Ebay gives this modules based on BK3231S chip
(with 5 pins)
We need to remove one R0 rezistor
Solder 1uF cap SMD 0402
Then solder any kind of LDO stabilizer in SOT23. (AP2210N-3.3TRG1 or MCP1754ST-3302E/CB or XC6206 3.3V)
...repeat it ...
...and that's all FOLKS ......
Stabilizer MCP1754ST-3302E can handle 16V input ... ideal for automotive use ...

Hey JRD would you be interested in building me a few of these. I can desolder but would have trouble soldering the cap.
