ClockTHREE v2

Although ClockTHREE v2 is yet to be officially introduced by the Wyolum team, I could not resist the temptation of showing off this beautiful new board.

Compared with v1, v2 has a few new features worth mentioning:

• it can accommodate both piranha RGB LEDs and 10mm RGB LEDs (common anode);
• as real time clock, supports DS1307, DS3231 and ChronoDot and wyolum's own rtcBob;
• three kinds of different coin battery holders (for RTC backup battery) are supported;
• the power socket can be mounted in 3 different places;
• no more tweaking of the terminals is required when using the 10mm RGB LEDs.

The other great features are intact:

- relatively easy to build for such a large and complex kit, with well-written documentation, both on-line and on PCB's silkscreen;

- Arduino (ATmega328)-compatible: uses Arduino IDE for sketch upload;

- display consists of 16x10 RGB LEDs + 16x2 single-colour LEDs;
- on-board speaker/buzzer for the alarm;

- word-clock functionality, user-settable time and date etc.

An assembled ClockTHREE v2, with piranha LEDs, is shown in the photo below. 

A new baffles design is in the works.
Should be offered in the store anytime now.
