Hardware Connection & Drivers Guide

Connect Microcontroller via Data USB Cable

Ensure your development board (ESP32 DevKit, ESP8266 NodeMCU, Arduino Uno/Nano, etc.) is connected to your computer via a high-quality USB Data cable (not charge-only).

Install USB to UART Drivers & Fix Permissions

If your serial port does not show up in the browser connection dialog, your computer needs the USB-to-UART bridge driver corresponding to your board's chip:

Silicon Labs CP210x Drivers

Windows

CP2102 / CP2102N / CP2104 / CP2108

Standard USB-to-UART chip on DOIT ESP32 DevKit V1, NodeMCU v2, and official ESP32-WROOM boards.

CP210x Windows Drivers (.zip) SiLabs Official Hub

WCH CH340 / CH341 Drivers

Windows macOS

CH340G / CH340C / CH340E / CH341

Widely used on NodeMCU v3 (Lolin), Arduino Uno/Nano CH340 clones, and budget ESP32 boards.

CH340 Windows Driver (.exe) CH340 macOS Driver (.zip)

FTDI FT232 VCP Drivers

Windows macOS

FT232RL / FT232H / FT2232H

Used on standard FTDI USB-to-Serial breakout adapters and older Arduino Duemilanove/Nano boards.

FTDI Official Drivers

Linux Serial Port Permissions

Linux

Primary Ports: /dev/ttyUSB0 & /dev/ttyACM0

/dev/ttyUSB0 CP2102 / CH340 / FTDI UART

/dev/ttyACM0 ESP32-S2/S3 Native USB / Uno

Check if your board is detected in terminal:

ls -l /dev/ttyUSB* /dev/ttyACM*

Add your user account to the serial port group:

Debian / Ubuntu / Mint / Fedora

sudo usermod -a -G dialout $USER

Arch Linux / Manjaro / EndeavourOS

sudo usermod -a -G uucp $USER

🔄 Important: Restart your PC (or log out & log back in) after adding the group so Linux applies the new serial port permissions.

Manual Bootloader Mode Entry (If Flashing Fails / "Invalid head of packet" Error)

If flashing gets stuck at Connecting... or displays Invalid head of packet (0x73): Possible serial noise:

⚡ ESP8266 / NodeMCU / D1 Mini

Set Flashing Baud Rate to 115200 (crucial for ESP8266 stability).
Press and hold down the FLASH button (GPIO0 / D3).
Press and release the RST button once while still holding FLASH.
Release the FLASH button (Chip is now in Bootloader mode).
Click Program & Flash Firmware.

⚡ ESP32 / ESP32-S2 / ESP32-S3

Click Connect Device and select serial port.
Press and hold down the BOOT button (IO0 / GPIO0).
Press and release the EN / RST button once while holding BOOT.
Release the BOOT button.
Click Program & Flash Firmware.
