Deauther Watch V2 ESP8266 Programmable Development Board | Smart Watch | Arduino | NodeMCU
Deauther Watch is still an ESP8266 development board, but you can wear it like a smartwatch.
This ESP8266 development board comes with an 800mAh battery, OLED display, and a 3-way momentary slide switch.
It comes installed with the latest ESP8266 Deauther software. With this software, you can perform different attacks to test WiFi networks.
Please note that the ESP8266 does only support 2.4GHz. For more details on the software, visit here.
You can also use it to develop your own software. It is simple to use, just like any other ESP8266 development board.
TTGO T-Watch Programmable Wearable Environmental Interaction WiFi Bluetooth Lora ESP32 Capacitive Touch Screen
TTGO T-Watch is a programmable and networkable open-source wearable device that can be used like a smart watch. It supports all the major programming languages like KB-IDE, Arduino, Micro python, Pictoblox for programming the watch.
Because the main core of the watch is an ESP32 chip it is having in-built capabilities of WiFi and Bluetooth. So without using any extra modules itself this can be very useful for IoT wearable projects and applications.
The capabilities of T-Watch can be expanded with a bunch of changeable modules like if you need GMS capability for your watch then you can connect SIM800L module or if you need GPS the you can connect the GPS module. The possibilities of this modular concept is wide, checkout the list of all modules supported by the T-Watch below.
- LoRa + GPS
- Heart Rate
This is not a watch but an opensource smartwatch OS, AsteroidOS is an opensource operating system available for LG G Watch Urbane, Asus Zenwatch 2, LG G Watch R, and many other watches.
Android Wear, the OS specialized for running on smartwatches, has changed the way we perceive wearables. From early-hardware gimmicks to actual, indispensable devices that improve our workflow and productivity, smartwatches have created their own niche in the Android ecosystem. They even extend beyond Android, thanks to the likes of Tizen and iOS, offering consumers a choice in hardware and software if they so desire.
But, what if you want an OS on your hand (quite literally at that) that is entirely open source? What if you wish to have complete control over how your data is handled, how your watch behaves and how easily and quickly it is updated? What if you simply want to escape the clutches of big name corporations and go for something that is much more community oriented and not hungry to know everything there is to know about you?
Well, now you do have a choice. AsteroidOS is an open source operating system, designed to be run on smartwatches.
Developed by Florent Revest, AsteroidOS is a flavor of Linux for smartwatches. The OS is still in early beta stages, and as such, only has basic smartwatch functions and features like a calculator, calendar, stopwatch and heart rate monitor and cannot replace Android Wear as your daily driver completely.
AsteroidOS unleashes the potential of your watch with up to 48 hours of autonomy and a set of apps including everything you need on a smartwatch: an agenda, an alarm clock, a calculator, a music controller, settings, a stopwatch, a timer, and a weather forecast app.
