Clockwise is an open-source smart wall clock that you can easily build yourself.
It only needs:
- 64x64 RGB LED Matrix (HUB75 or HUB75E)
- ESP32 dev board
- 5V 3A power supply
- Jumpers
To simplify assembly, you can also use the WiseShield-32 DIY PCB kit β created in partnership with Elecrow especially for Clockwise.
- Real-time clock with customizable themes ("Clockfaces")
- Web-based interface for configuration
- Open-source hardware and firmware
- Compatible with various PCBs or just simple wiring
- Community-driven
If you want to build it from scratch, you will need at least these components below. Follow the instructions on Wiki to assemble it.
- 64x64 RGB LED matrix (HUB75 or HUB75E)
- ESP32 Dev Board
- 5V 3A power supply
- Jumpers
Alternatively, we created a custom PCB that simplifies this process a lot. The kit includes not only the PCB but all components including sensors to make your clock smarter. Check the WiseShield-32 PCB kit out now!

You can choose from many creative Clockfaces β or make your own:
| Mario Bros | Words | World Map | Castlevania | Pacman | Pokedex | Canvas |
|---|---|---|---|---|---|---|
Canvas is a special type of Clockface that is capable of rendering different themes described in a JSON file. More about Canvas Clockface: Wiki page
You can start developing and customizing Clockwise in two different ways:
- PlatformIO β advanced usage for developers
- ESP-IDF β for full control
π Both are described in the Flashing section of the Wiki
Clockwise offers a flexible set of options that you can adjust through its built-in Settings page:
- WiFi settings β easily update your network details without reflashing
- Timezone & NTP server β sync the clock accurately for your region
- Display brightness β manual or automatic control (with optional LDR sensor)
- Display rotation β adjust orientation to match your wall setup
- Clockface selection β switch between installed Clockfaces or use Canvas themes
- RGB order correction β fix color mismatch on certain LED matrices
- POSIX timezone string β fine-tune timezone behavior
