Specifications

Key Features

• Plug-and-Program Design: Snap your ESP-01 directly onto the 2x4 header - no jumper wires, no breadboard, no soldering needed.
• Reliable CH340G Chipset: Proven USB-to-serial converter with stable communication and wide OS driver support.
• On-Board 3.3V Regulator: Safely powers the ESP-01 at 3.3V from the 5V USB bus, protecting the ESP8266 from overvoltage.
• Dedicated Flash Mode Control: Built-in button or switch pulls GPIO0 LOW so you can enter programming mode with a single press - no manual wire grounding.
• TX/RX Activity LEDs: Visual feedback during data transmission helps with quick debugging.
• Compact USB Stick Form Factor: Plugs directly into any USB-A port; small enough to carry in a pocket or tool kit.
• High Baud Rate Support: Communicates at up to 2 Mbps for fast firmware uploads and serial monitoring.
• Cross-Platform Drivers: CH340 drivers available for Windows 7/8/10/11, macOS, and all major Linux distributions.
• Arduino IDE Ready: Select "Generic ESP8266 Module" in the Arduino IDE board manager, pick the COM port, and upload your sketch immediately.
• Serial Debug Console: Also functions as a standard USB-to-UART adapter for serial monitoring and AT command interaction with the ESP-01.
