Hello, complete newbie here. As the title suggests, I have a problem when trying to power on a ws2812b led strip.
I'm using a breadboard power supply connected to a mobile power bank (Output: 5V 3A) The power supply works normally when powering a nano through the 5V pin
I tried to power a strip of ws2812b led (68 leds) with the same 5V bus. As soon as the ground and 5V pins of the strip gets plugged into the bus, the led on the power supply shuts off and so does everything powered by it. The data pin was not plugged into anything.
Upon further inspection with a multimeter, the seemingly off power supply was actually still providing less than 1V into the 5V bus.
When the pins to the led strip gets disconnected, everything returns to normal. Power supply lights up, nano boots up, etc.
Breadboard Power supply in question (Breadboard power module, circuit test power supply, switchable voltage 3.3/5v|Integrated Circuits| - AliExpress)
What may be the cause of this, and how can I fix it?
