I'm really new at electronics and wiring, so please be kind. Coding is my stuff, but I'm trying to learn something here.
I'm working with a project to store the movements of a skateboard through a MPU 9235 and the idea is to save the output of the sensor to a MicroSD.
I have both components and acquired a LiPO 3.7v 400mAh to take everything off the protoboard and attach at the bottom of the skateboard.
The code is working, everything code wise is working ok, but I'm strugging to understand how to power both MicroSD module and MPU9235, since both have the VCC pin (VDD in some versions).
The current connections are replicated in Fritzing. Only replacing Arduino Uno for an Arduino Nano, and the MPU 6050 from the picture for a MPU9235.
My first thought was to connect the LiPo battery into VIN and GND pins of Nano. From there I believe that I can wire up the 3V3 output directly to VCC from MPU9235.
But what about the MicroSD module?
How would I power its VCC pin since I have no 3V3 pin left? I read that it's not right to use a digital pin as power output.
How can I connect two components that needs power from external source?
