This is a simple setup of Arduino Nano 33 BLE Rev2 with battery control module, a SD card adapter module and a battery [IMG-20250312-WA0039] Please check the wiring I think I am messing up the ground, I'm new to this and is there a specific way the wires are to be structured Thanks

It looks good, but there is a pinned post in every category you should read. It will tell you how to do the wiring and a few other important things. It is called 'How to get the best out of this forum'

Hmmm sorry bruh but didn't get you [image] How to make a schematic you can post. Tutorials When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; howev…

Yes, but don't get too hung up. A picture of a hand drawn is fine. One of the important bits is Remember, where you can, INPUTS go to the left, OUTPUTS to the right, positive voltages to top and negative to bottom. Make sure the picture is in focus. Print labels in a black ink or similar so it …

Output to the left hmmm, here the outputs are mainly on the Arduino sooo lemme try rearranging

[image] NewbieeeUno: lemme try rearranging Nay.

The SD module in your drawing is a 5V device so it won't work out. Since you found a topic with one of my SD implementations you can see that I used one of those much smaller modules - they are 3V guys, no level-shifting hassle/s.

[image] NewbieeeUno: Can someone help me out with the circuit diagram the one with just the lines symbols... Why do you want one? Except for what @anon85221860 pointed out, the diagram in post #1 is fine.
