Solder: Time II Watch Kit


The Solder: Time II is the latest version of our Solder: Time Watch Kit.


The Solder: Time II Watch Kit is an upgraded version of our Solder: Time Watch Kit. This new version is more hackable than ever. The Solder: Time II uses the same ATmega328P microcontroller used in the Arduino UNO, allowing you to program it using the Arduino software.

The Solder: Time II has a very impressive display. Four 5x7 LED matrix modules gives you control of a 7x20 matrix for a total of 140 LEDs! The new LED matrix allows for an amazing amount of information to be displayed; time, date, month, words, scrolling messages, graphics, special characters ... the possibilities are endless. The STII also has a piezo buzzer for the alarm. You can also use it to add sounds to you custom programming or even write games that you can play on your wrist!

The watch comes preprogrammed and requires soldering and assembly which should take less than one hour.
