Title : Bluetooth Module circuit
ANALYSIS
-Bluetooth Module is no need to be soldered
on its pin as compare to the other circuits that have been done in previous week
since it is just “Plug & Play”.
-The Bluetooth module works on 3.3V level
only. High voltage like 5V will permanently damage the module. Therefore, if application
requires to be operated at 5V then use a LM1117-3.3 regulator to convert the 5V
level to 3.3V level as required by module. By considering this factor, I have
to add the LM1117T circuit since the supply voltage from the PIC is 5V. From
here, LM 1117T will do its task by reducing the voltage from 5V to 3.3V as
required by HC-05 Bluetooth Module.
