No, it is proprietary. sorry.

CAN GET THE spec sheet on the processor and using reverse engineering and trace the wire and connection very easy to do,mostly its simple 3.3 volt regulator circuit and 5 volt regulator circuit,simple clock circuit ,reset circuit uses 2 resistor and the pins from the cpu to each of the output pins on the board

@Pravnav What do you want the circuit diagram for?

DONT really have to reverse engineer it ,can easy look at arduino circuit it almost the same But whats good about this if you have a bad board its very easy to troubleshoot it.

THATS only reason someone wants a schematic ,no other

I think DJ doesnt have the time to put up the circuit,circuit is a very common used circuit for microprocessor,no special about about

Hi @Rich,

I was jus wondering that such small controller is very versatile... I was jus eager to know about it... Noting specific or serious...

I have the pdf file on microcontroller but its very easy to find look under the bluetooth module for the part # and do a search for it.

Yeah, it's a PIC 18LF4685 microcontroller... I found the datasheet for it... Thank you...

@Herr ball there is a fuse inside the chip that protects the chip first from getting info on the chip using a programmer and second protects the chip so you cant write to it.

Does that explain it better
