I have a problem with my breadboard jumpers. They overheat when I try to power many LEDs, but we're "only" talking 5.05V at 2.1A.
The wires are really thin and they melt after 10-15 minutes of constant use. Even the breadboard melts where the wires are installed. I know it's not ideal to use thin breadboard wires for this, but since I'm powering this together with an ESP8266, I need to use relatively thin wires.
The wires going to the LED strip are about the same size as the breadboard wires.
What alternative do I have to this? I tried installing a fan inside my cylinder (LEDs wrapped around the cylinder), but it's not powerful enough to cool them down.
