Hi everybody,
I want to create a circuit which involve arduino Pro Micro, BLE breakout board and GSM breakout board.
I would like to know how to give power to these three.
For Arduino ProMicro, there is no big deal. I know how to do it? That require 5V
For BLE breakout board, that also require 5 V.
For GSM breakout board, that also require 5V.
For accelerometer, it require 3.3 V.
Do I need to give 4 different power(four different DC adapter) source by connecting ground together?
Can I used only two, 5V for ProMicro, BLE and GSM and 3.3V for accelerometer. If I can, how to connect these three to power line (in serial or parallel).
Kind Regards,
John
