will Ihad the purple one of these I bought outside and it was barely visible in daylight. I don't think it was anything to do with it being sunlight - they are just not super bright.

will Ihave mine mounted on the ceiling and got it working fine. Most software supports mirroring and flipping of the image at output time - including the app they suggest.

will Itis an NTC 100K thermistor - the same type that is in the Ender 3 by default. I made a 1:1 switch on my machine rather than put this whole hotend my machine. The milling around the thermistor seemed way too large and would need a thermal compound to conduct to the block well. Thermistor and heater cartridge worked just fine though.

will This board is suitable for DIY printer so long as your build will not exceed 15A total draw going through this board. The traces in the board are rated just above the 15A mark.

will It depends what connectors your referring to - there are a number of them. For power it's screw terminals. For steppers it's dupont inputs, for steppers it's JST connectors. There are other connectors too depending on what your looking to attach.

will I never measured it with an oscilloscope or anything like that but I've used these for basic led strip lights drawing 3A at 5v bucked from 12v and I also boosted 5v to 12v at 2A. There was no voltage dips at that point (there is an alright smoothing capacitor on the output). I wouldn't push the much farther than that to power high drain LEDs because they got very hot how I used them. Youd want a heatsink on the regulator or maybe even a fan. At that point your better off just using a more well suited power supply I reckon.

will Notsure about this, if it has the same mounting holes as an Ender 3 and you can adjust the position on your z limiter to account for it possible different size then should fit.

will You can, the camera includes IR leds to iluminate what it's looking at as well and switches to IR mode when it is in low light. I have not tested the distance it can cover as I use these inside a small hallway and small room.
