DSTIKE Deauther Watch Y II — ESP8266 Wi-Fi Testing Tool

A Refined ESP8266 Wi-Fi Development Watch

The DSTIKE Deauther Watch Y II is the updated version of the Deauther Watch Y, designed for makers, firmware developers, wireless technology education, and authorized 2.4 GHz Wi-Fi testing.

This revision brings three practical refinements: a clearly visible RGB indicator on the front panel, an optimized charging circuit, and hex socket screws for a cleaner finish. It retains the original Watch Y's ESP8266 platform and core hardware specifications.

With a 1.3-inch OLED display, a built-in 1000mAh rechargeable battery, USB-C connectivity, an external antenna, and a soft silicone strap, the Watch Y II brings a portable Wi-Fi development setup to your wrist or workbench.

Wireless support: 2.4 GHz Wi-Fi only.

What's New in Watch Y II?

A More Visible RGB Indicator

The original Watch Y's RGB LED sat beneath the upper board, where it was harder to see. The Watch Y II uses a reverse-mounted LED arrangement that makes the light directly visible through the upper board on the front of the device.

This makes RGB feedback easier to check while using the watch. The LED remains programmable for custom status indications, notifications, and lighting effects. Its colors and behavior depend on the installed firmware.

An Optimized Charging Circuit

The charging circuit has been revised as part of the Watch Y II hardware update. The watch retains its built-in 1000mAh rechargeable battery and USB-C connection for charging and firmware flashing.

Hex Socket Screws

Hex socket screws replace the original Phillips screws, giving the enclosure a cleaner, more cohesive appearance alongside the black circuit boards and transparent case.

Watch Y vs. Watch Y II

What Can You Do With It?

The Watch Y II arrives with compatible ESP8266 Deauther firmware installed. Available functions depend on the firmware version and may include:

• Network scanning: Discover nearby 2.4 GHz Wi-Fi networks.
• Signal and channel observation: View signal-strength and channel information.
• Packet monitoring: Observe supported wireless packet activity.
• Authorized protocol testing: Explore management-frame behavior and beacon/probe demonstrations on compatible networks in a controlled environment.
• Clock display: Use the display and onboard RTC hardware for timekeeping.
• RGB feedback: Display firmware-defined colors and custom visual indications.
• Web configuration: Access supported firmware settings, including device and SSID configuration.

For custom projects, use the Arduino IDE to develop applications that work with the display, navigation switch, RGB LED, RTC hardware, and expansion pads.

Hardware Highlights

• ESP8266 ESP-07 module with 4MB flash: A familiar platform for ESP8266 firmware development.
• 1.3-inch SH1106 OLED: A monochrome display for menus, network information, packet activity, and the clock.
• Three-way navigation switch: Scroll up, scroll down, and press to confirm.
• 1000mAh rechargeable battery: Supports approximately 9–10 hours of typical active use, depending on operating conditions.
• USB-C connectivity: Charge the battery and flash compatible firmware.
• Included external antenna: Offers flexibility in antenna positioning and compatible antenna selection.
• Visible programmable RGB LED: Check light feedback directly from the front panel.
• RTC hardware: Provides dedicated timekeeping hardware for supported clock functions.
• Expansion pads: Connect compatible sensors or develop additional features.
• Transparent enclosure and silicone strap: Use the device as a wearable tool or a compact development platform.

Technical Specifications

Power, Charging, and Indicators

The Watch Y II includes its 1000mAh rechargeable battery, so no separate battery purchase is needed.

The charging indicators and the programmable front RGB LED serve different purposes. Refer to the installed firmware's documentation for the meaning of front RGB colors.

Typical active runtime is approximately 9–10 hours. Actual runtime depends on battery condition, display use, Wi-Fi activity, RGB brightness, firmware settings, and connected hardware.

Antenna and Wireless Performance

An external antenna is included with the Watch Y II. Wireless performance depends on the antenna, device orientation, access-point transmit power, channel congestion, walls, and the surrounding environment.

The Watch Y II retains the original Watch Y's wireless platform and antenna configuration. Operating distance varies with the setup and conditions.

What's in the Box?

The standard Watch Y II package includes:

• 1 × Fully assembled DSTIKE Deauther Watch Y II
• 1 × 1000mAh rechargeable battery, already installed
• 1 × External antenna
• 1 × Soft silicone watch strap
• 1 × USB-C data and charging cable
• 1 × Quick-start guide

Open-Source Firmware and Custom Development

The Watch Y II works with the open-source ESP8266 Deauther ecosystem. Developers can use the Arduino IDE to create wearable sensor displays, Wi-Fi signal monitors, clocks and timers, RGB notification devices, or custom menu interfaces.

• ESP8266 Deauther source code
• Deauther usage documentation

Hardware Connections

Compatibility and Intended Use

The Watch Y II supports 2.4 GHz Wi-Fi only. It does not support 5 GHz Wi-Fi, Wi-Fi 6, cellular data, or SIM cards.

Scanning and supported testing functions depend on the installed firmware, channel, network hardware, and security settings. Protected Management Frames (802.11w/PMF) can limit or prevent certain management-frame tests. The device does not bypass PMF protection.

Designed for education, firmware development, wireless observation, and authorized network assessment. Use testing functions only on networks and equipment you own or have explicit permission to test. The supplied firmware is experimental, and available features may vary by version.
