Deauther Mini V4 ESP8266 Development Board with RTC Programming WiFi Penetrating Testing Intelligent Hardware DIY

Introduction:
- DSTIKE Deauther MiNi V4 is a compact, open-source ESP8266 development board designed for wireless education, firmware experimentation, network diagnostics, and authorized 2.4GHz security assessment.
- It combines a 1.3-inch OLED display, three physical control buttons, an addressable RGB LED, a high-brightness LED, onboard battery charging, and an external antenna connector in a pocket-sized platform.
- Compatible ESP8266 Deauther firmware is preinstalled, allowing supported functions to be operated directly from the display and buttons. No phone or computer is required for basic standalone operation.
- MiNi V4 can also be reprogrammed like a conventional ESP8266 development board, making it suitable for custom firmware, for Ar-dui-no projects, portable wireless tools, and electronics education.

Compared with Deauther MiNi V3, the V4 hardware includes several important improvements:
- The previous PH2.0 battery connector has been replaced with a smaller PH1.25 connector.
- Updated battery-connector orientation.
- Added input-protection diode to help prevent current from flowing back into the USB connection.
- Repositioned onboard components for improved layout and heat dissipation.
- Re-optimized charging circuit for more stable operation.
- Updated packaging and instruction manual.

Battery Compatibility Warning:
- MiNi V4 uses a different battery connector from MiNi V3. Do not connect an older battery without confirming the connector type and polarity.
- Battery-connector polarity should always be checked before connection. Incorrect polarity may permanently damage the board and is not covered as a manufacturing defect.

Supported Learning and Assessment Functions
- Available functions depend on the installed firmware version and configuration.

2.4GHz Wi-Fi Scanning
- Scan nearby compatible 2.4GHz Wi-Fi signals and review information such as network identifiers, channels, and signal activity.

Packet Monitoring
- Observe selected packet and channel activity to better understand how nearby 2.4GHz wireless environments behave.

Management-Frame Resilience Testing
- Evaluate how equipment on an authorized test network responds to selected 802.11 management frames.
- This function is intended to help network owners identify older equipment that may not support modern management-frame protection.

Beacon-Frame Demonstration
- Demonstrate how beacon frames are used to advertise wireless network information in a controlled laboratory environment.

Probe-Frame Demonstration
- Explore how compatible client devices use probe requests while searching for known wireless networks.
- These functions do not reveal Wi-Fi passwords, decrypt protected traffic, or provide access to secured networks.

Hardware Highlights:
- Ultra portable design: a true 'pocket sized' device. Whether you're testing at a local café or giving a presentation at a cybersecurity conference, it's easy to carry and ready to use at any time.
- Intuitive visual operation: equipped with high contrast OLED display screen and physical buttons/scroll wheel on the body. You can independently browse menus and perform tests without connecting to a computer or smartphone.
- Excellent scalability: Built in power management system, supporting direct connection and charging of lithium batteries. The external antenna interface facilitates easy replacement of high gain antennas, greatly expanding the signal coverage range.
- Open source and programmable: It is not just a testing tool, but also a standard ESP8266 development board. You can adopt for Ar-dui-no IDE for secondary development and flash your own custom firmware.
