The Open Smartwatch, which can be purchased for $37, is the product of an open-source project. The Lite Edition will be available for purchase tomorrow, and a GPS version will be released in the distant future.
ESP32 technology is used to create the device. This microcontroller is a low-cost system-on-a-chip solution with integrated WiFi and dual-mode Bluetooth connectivity. It also consumes very little power. The clock was developed by “Paul’s 3D Things” and comprises hardware modules, cases that can be printed using 3D printing, and a bespoke operating system based on C++/Arduino/PlatformIO. Everything is made with free, open-source software and stored on the GitHub platform.
The Watch has a unique appearance when taken as a whole. Regarding whether or not we approve of it, we can’t make up our minds. But there is no denying that it possesses personality. Having said that, you won’t be fooled into thinking that it’s a Garmin or an Apple Watch.
Open Watch is genuinely one-of-a-kind, not just in terms of its appearance but also because it can be assembled, repaired, and customized by anybody. YouTube videos can be watched as references or for assistance with the assembly process. Therefore, the wristwatch is geared more toward people who enjoy DIY projects and hobbies. Additionally, it may excite the interest of those who wear Pebble watches.
The following is a list of the Open Smartwatch’s technical specifications:
- EPS32-micro-D4: 2x240MHz, 320KB RAM
- Bluetooth 4.2 BR/EDR BLE
- WiFi 2.4GHz 802.11 b/g/n
- GC9A01 240×240 16bit TFT display (round)
- BMA400 Accelerometer + Pedometer
- MCP73831 LiPo Charger
Although there is not a heart rate monitor or any other advanced tracking for health and fitness, the accelerometer has the capacity to count steps, measure distance, and do other functions. The Light edition has the features mentioned earlier and can be purchased for $37. Makerfabs currently offers this for sale on their platform.
In the not-too-distant future, another edition of GPS is planned. Because development is still ongoing, this is presently in the pre-release phase. The following are examples of additional hardware on that one:
- Quectel L96 GPS module
- 4MB RAM
On the project sites, it is mentioned that the Open Watch project is still in its infancy at this point. Shortly, you can purchase the Watch in its assembled state. For the time being, to put the item together, you will need either a reflow station or a hot air gun. You can hand solder everything if you don’t need the accelerometer in the first place.
The alternative is to construct the Watch by procuring all its component parts separately and starting from scratch. Everything can be purchased on AliExpress, and the GitHub page for the Watch includes a list of the components that you will need, along with links to where you can get them.
There are other open source smartwatches besides Open Watch on the market today. PineTime is a $25 open-source device that has been the subject of previous articles on our site. The software for the Watch is currently being developed with the support of members of the wider Linux development community. This indicates that the eventual feature set of PineTime will largely depend on the level of interest shown by developers.
