I am working on a project where a Wemos D1 Mini (ESP8266 breakout) controls an WS2812b (Adafruit) digital led strip. This works fine, but I found that the Wemos gets a little bit hot, and stops working after a few days.
The wires are connected 5V - 5V, GND - GND, D4 -> Din, so without any external components. It is powered by a 2.2A 5V USB adapter.
My electronics knowledge is limited, but I would have thought that the 5V bypassed any other components (such as voltage regulators) entirely. However, this seems not to be the case, hence the high temperature.
Could this be fixed easily, by adding some components?
Thank you in advance!
