I personally went for flashing over a USB TTL adapter using the Arduino IDE. It is important to notice, that the TTL adapter needs to provide 3.3V, not 5V! Also i recommend using a PL2303 based USB TTL adapter, as others did not work for me (spent hours trying until I finally gave up and tried with a PL2303 based one I had laying around). Another important Point was, how to enter the programming mode: Hold down the pushbutton while connecting only the power pins. Leave at least one of the two data pins disconnected. Then let go of the button and connect the RX and TX (crossed). Flasing did not work for me when i connected all wires at the same time while holding down the button. | I personally went for flashing over a USB TTL adapter using the Arduino IDE.

this might be different in your setup, but I would like to install the npm modules globally and then run them as non-root users through a systemd script to make sure they are auto-startet as soon as my system boots. | this might be different in your setup, but I would like to install the npm modules globally and then run them as non-root users through a systemd script to make sure they are auto-startet as soon as my system boots. | ||
