Hi, I’m designing a modular led matrix pcb with tlc5940s chips which will be connected to a teensy 3.2 and a raspberry pi. To be honest, I don’t have a great understanding of how power works and I’m seeking advice on what type of power supply I should use to power both the LEDs and the raspberry pi.
The teensy will be powered over usb from the pi and the tlc5940 chips will be powered from the teensy vin pin. I’m planning on eventually scaling the project to over a 1000 LEDs, so I’d like to know what type of power supply I could use to power both the Pi and a 1000 LEDs (all at once with full brightness) and how I might calculate what power supply I should use should I decide to power more than a 1000. These are the LEDs I’m planning on using.
