This is my first time here so sorry for any wrong formatting.
I am currently creating a project where I will run my wall with 10 meters of addressable LED strip (Made up of 2 x 5 meters rolls). I have two 20 amp, 5 V power supply for the project. After calculating 60 LEDs/meter at 5 V it would consume around 18.8 W/meter meaning that at 10 meters it would be 188 W, 5 V = 37.6 amps.
I searched a lot but don't have the necessary understanding of electrical engineering to safely conclude what I am going to do. Below I made up two different scenarios which I could wire up, my two questions are:
- Are my scenarios safe? / Would they work?
- Is there any recommendations or changes to my schematic?
To control the addressable LEDs I am using a microcontroller board called NodeMCU, which would acquire 5 V from the power supply and send the data signal through the LEDs.
Case 1
For the first case I would have each power supply connecting at one end of the strip and both strips connected together in the middle for power and data, meaning I would not have any voltage drops. The NodeMCU would acquire 5V from the first power supply and send data through one end.
Case 2
Case 2 is similar to Case 1 but the only difference is that there wouldn't be a connection between both strips and the NodeMCU would transmit data at both ends otherwise one strip wouldn't receive data.
I appreciate any opinions and suggestions to my schematic, thank you!
