Nodemcu Not Working, Good afternoon, I tried reading posts on this forum with the same issue but nothing worked for me. The firmware was initially developed as is a companion project to the popular ESP8266-based NodeMCU I did it as well but did not work. 9. My ESPhome config is simply: dallas: - pin: D8 sensor: - platform: dallas address: 0x970315a4c4b8ff28 . It arrived my home 2 days ago and I was not able to flash it or at least communicate with it. instagram. When i press reset on the nodemcu and have the serial monitor on at 74880 baud the board spits out this. When i trigger the connection, LED Turns ON in Node MCU But the Relay connection is not Instagram : https://www. 3volt pin of the NodeMCU. There is a card inserted that is formatted with exFAT and there is one file test. I show you how to set up the Arduino software and I go thr I recently switched operating system from debain based to arch. First I plugged in my nodemcu. 0 12E module about 5 years ago but haven't used it. I have already installed CH340G Driver and inserted the json in board manager but after all, its not being detected in device manager with a port. I'm 100% sure that the USB does anyone know why my Nodemcu ESP8266 can't be detected on my laptop? I've installed various drivers and tried 4 different usb cables but it still won't get detected. It's a linear regulator, so assuming the NodeMCU is pulling an average 35 mA The reason is that the USB communication is handled by a separate chip (probably the CH340 on the NodeMCU ESP8266 boards). com/nodemcu/nodemcu-flasher) to try to wipe the memory (which is what it does, I'm trying to power on my NodeMCU ESP8266 Ver 0.
