OPEN HARDWARE. REAL POSSIBILITIES.
An open smartwatch platform for developers, researchers and ideas worth wearing.
Hardware, firmware and mechanics. Yours to explore.
01 / WHY WE BUILT IT
We wanted a platform to collect and process wrist data, with hardware and software we could change. So we built one.
Hacktor Watch brings sensors, a display, connectivity and audio into something you can actually wear. Start with the existing designs, write your own application, and see what happens when your code leaves the desk.

02 / OPEN IT UP
A wearable is a whole system.
Get to know the parts you can build with.
HACKTOR WATCH 2.0 / PCB01 / COMPUTE
The heart of the experiment.
A dual-core microcontroller with Wi-Fi and Bluetooth Low Energy, ready for sensor acquisition, your interface and application logic.
02 / MEMORY
Code, buffers and bigger ideas.
External NOR flash and PSRAM give the platform room for applications, assets and working data. How you use that memory is part of the experiment.
03 / MOTION
Start with a movement.
A six-axis accelerometer and gyroscope gives your application a view of wrist motion. Explore raw data, gestures and the sensor’s embedded step counter.
04 / INTERFACE
Make your application tangible.
A colour LCD with capacitive touch is your canvas for watchfaces, complications and new interactions. Create your own interface or build on the existing examples.
05 / AUDIO
A starting point for local intelligence.
The microphone and speaker amplifier open up audio experiments. A small wake-word detector has already run on the watch using TensorFlow Lite Micro.
06 / HAPTICS
Give an interaction a physical response.
A dedicated haptic driver lets you explore tactile notifications and feedback as part of a wearable interface.
07 / POWER
Understand the whole device.
Charging, fuel gauging and separate power converters make power behaviour part of the design you can inspect and control.
Hardware capabilities. Driver and application support depend on the firmware you choose.
Explore the layers03 / MAKE IT YOURS
The enclosure is part of the platform, too.
Explore the case, understand the assembly and adapt the physical design to your project. The mechanical files live alongside the electronics and firmware.

Start with the tools you know.
Explore another stack when you’re ready.
The Arduino example is a practical way into the hardware. Explore an analog face, step counting, wrist wake, battery indication and BLE time synchronisation.

05 / LEARN FROM THE WHOLE DEVICE
Pixels use memory. Radios use energy. Sensors have timing requirements. Hacktor is a place to understand those trade-offs through the device you’re building.

A FEW THINGS TO KNOW
Hacktor is an open wearable platform for development and experimentation. For PCB and developer-kit enquiries, contact the project team. Package contents and availability will be announced when they are defined.
The hardware, firmware and mechanical designs are published in the project repositories. Start with the design files and the instructions for your chosen firmware. Assembly requires appropriate electronics tools and experience.
Arduino is a practical route for rapid experiments. NuttX offers a POSIX-oriented environment, while Zephyr combines an RTOS, hardware description and configurable services. Explore the software section for the current examples and supported features.
A small wake-word detector has run on Hacktor Watch using TensorFlow Lite Micro. Model size, working memory, audio processing and listening time all affect what fits your application.
Write to contact@hacktorwatch.com and tell us what you’d like to build. An enquiry does not place an order or involve a payment.
