Digital LED Clock Kit, simple and quick to assemble (about 20 minutes build time). The clock is powered by a pre-programmed 8051-compatible microcontroller.

Specifications:

  • Board size: 70 x 90 x 15 mm
  • Power supply: 5V (internal), or 6.5-12V (external)
  • Assembly: Includes English schematic and Chinese instructions, but assembly is straightforward without needing to read Chinese
  • Operation: Clock can be fully set using only 1 push button

Battery note: The onboard CR2032 socket is not functional for backup power, as it would also attempt to power the display, causing excessive drain and MCU instability. Please ignore the coin cell socket.

The Digital LED Clock Kit is a beginner-friendly exercise for soldering and building a functional digital clock.

    Fun soldering practice project and you end up with a digital clock. Be careful when soldering some components as they have polarity and must go in the correct way. There are some good online tutorials you can follow if you’re not sure. I found the LED colons between the digits a little too bright so I took out the associated resistor (R2) and left them off, but you could just put in a larger resistor, say 1K vs 470 to make them dimmer. It’s not a high quality PCB so if you mess up and have to de-solder something, be careful you don’t break the traces. Lastly, one site recommended to not use the button battery as it will eventually cause the micro controller to freeze up. I power it from the screw terminals with a DC power supply and it’s been working fine and keeping good time. 24 hour format only.
