BEWARE: Maximum continuous current depends on cooling
The Maximum continuous current of the ESP32 Dagor Controller depends on the quality of heat-sinking and cooling. A small heat-sink or a cooling fan can have great impacts on the maximum continuous current the board can handle. The on-board temperature sensor is a great way to assure you don’t exceed the maximum operating temperature. Ask the community about it!
