Air quality + CO₂ alerts
Maximize your comfort and productivity by measuring CO₂ levels, temperature, humidity, and VOC levels (volatile organic compounds).
Customizable e-ink display
Select between current time and today's weather forecast using the companion browser tool.
Hackable + open source
3D-print your own case or create a new clockface app. Bitclock is unlocked + open source with 2.4 GHz Wi-Fi and Bluetooth 5 (LE) built-in.
Have a 3D printer?
The Bitclock enclosure is a 3D printed design and you can optionally assemble a Bitclock yourself. Order the Bitclock PCB, insert it into your print, and snap it together. No other parts needed!
