DSTIKE Deauther32 Watch SE — ESP32-S3 Watch

Expandable ESP32-S3 Wi-Fi Development Watch

The DSTIKE Deauther32 Watch SE is an open-source ESP32-S3 development platform built in a portable watch-style enclosure.

It combines a 1.69-inch IPS color display, 1000mAh rechargeable battery, microSD storage, DS3231 real-time clock, AXP2101 power management, external antenna support, two programming interfaces and 13 breakout GPIOs.

Compatible Deauther32 firmware is preinstalled for wireless education, signal monitoring, network diagnostics and controlled assessment of authorized 2.4 GHz networks. Developers can also replace the supplied firmware and use the hardware for custom Arduino or ESP-IDF projects.

Important: The Watch SE supports 2.4 GHz Wi-Fi only. It does not support 5 GHz Wi-Fi.

These functions are intended for wireless education, laboratory demonstrations, network diagnostics and authorized testing.

The device does not reveal Wi-Fi passwords, decrypt protected traffic, provide access to secured networks or bypass Protected Management Frames.

1.69-Inch IPS Color Display

The 240 × 280 ST7789 display provides more space than the smaller monochrome displays used on earlier ESP8266 watches.

It can show:

• Firmware menus

• Network and channel information

• Signal data

• Packet-monitoring status

• Clock information

• Battery and operating status

• Custom graphics

• Sensor readings

• User-created interfaces

Screen contents and menu options may vary between firmware versions.

Three-Way Navigation Control

A compact three-way control provides direct menu operation:

• Scroll up

• Press to confirm

• Scroll down

The control can also be reassigned in custom firmware for games, menus, application shortcuts or other user-interface functions.

microSD Storage

The built-in microSD slot can be used for compatible projects involving:

• Configuration files

• Data logs

• Images and interface resources

• Sensor records

• Custom application files

• Firmware-related data

A microSD card is included.

Available functions depend on the installed firmware and card format. The presence of a microSD slot does not mean every firmware version automatically records wireless data.

DS3231 Real-Time Clock

The onboard DS3231 provides dedicated timekeeping hardware for projects such as:

• Clock and calendar displays

• Timestamped data logging

• Scheduled actions

• Time-based sensor projects

• Portable timers

• Operating-history records

Some RTC functions in the supplied Deauther32 firmware may still be under development. Developers can access the RTC through compatible custom Arduino or ESP-IDF firmware.

External Antenna Support

The Watch SE includes an external antenna connection, allowing developers to select a compatible antenna for their project or authorized assessment environment.

Wireless performance depends on:

• Antenna type and quality

• Antenna orientation

• Access-point output power

• Channel congestion

• Walls and surrounding objects

• Local interference

• Firmware configuration

• Regional radio regulations

Using a larger antenna does not guarantee a specific range. Always use a compatible antenna and comply with applicable local radio regulations.

13 Breakout GPIOs

Thirteen accessible GPIO connections make the Watch SE suitable for hardware expansion.

Compatible projects may include:

• Environmental sensors

• External buttons and controls

• Status indicators

• Additional displays

• Data-logging modules

• Portable IoT controllers

• Custom input devices

• Educational electronics experiments

Use 3.3V-compatible signals and check ESP32-S3 pin assignments, boot behavior and current limits before connecting external hardware.

Native USB and UART Interfaces

The Watch SE provides native USB and UART-based development interfaces for:

• Firmware uploading

• Serial communication

• Debugging

• USB-enabled ESP32-S3 projects

• Recovery when testing custom firmware

Interface behavior depends on the selected firmware, USB mode and development-environment settings.

Power Management

The Watch SE contains a built-in 1000mAh rechargeable lithium battery managed by the AXP2101.

Actual operating time depends on:

• Display brightness

• Wi-Fi and Bluetooth activity

• microSD activity

• RGB LED brightness

• External antenna use

• Connected expansion hardware

• Firmware configuration

• Battery age and condition

Use a suitable 5V USB-C power source for charging.
