I'm very new to arduino and have started work on my first project, a simple little web server. I'm using a NodeMCU with an sd card module and screen. The issue is that in order to power my sd card module, I need to input 5V which the MCU doesn't provide.
In order to work around this I'm simply using an arduino nano as a power supply to pass into the vin input on the mcu.
What options do I have to exclude the need for the nano? Is there a simple module I can buy that acts as a power supply for 5v?
Any help would be great, thanks!
