  • I am no expert either, but my main purpose for treesitter is better syntax highlighting although it does other things as well. I think it is pretty common to use LSP and treesitter together e.g. Kickstart.nvim does it.

    Not sure how this relates to autocomplete. For that you usually have things like blink.cmp, coc.nvim or nvim-cmp. I think they mostly work together with an LSP, but maybe they can use the syntax tree from treesitter for that as well.














  • I have never used an ESP but as far as I can tell, you are right. There is no component involved for the 5V. Some boards have a diode and a fuse between VBUS (5V USB) and the 5V rail on the board, but that is not the case for the board in your picture.

    The black component with “512” is just a pull-down resistor for one of the CC lines of the USB connector. This should not get particularly warm.

    The brownish thing is the input capacitor of the voltage regulator. It can get a little warm due to ripple currents, but I wouldn’t expect a lot of heat.

    Are you sure it is not the black 5-pin voltage regulator for the ESP? As far as I know those ESPs can be a bit power hungry depending on what you have enabled (e.g. WiFi).

    Maybe you can check the temperature without your LED matrix connected and see if it is hot as well.
