Description

Clock Module as DIY kit, easy to asssemble (takes about 15 minutes). The clock program is on a pre-programmed 8051 compatible micro controller and supports dual alarm time, count down timer (max. 99 min.), stop watch and some other functions. The speed is in 10 steps adjustable, to achieve a higher precision.

The alarm output signal port 3.7 (pin 11) on the micro controller can also be used as digital signal to switch something else instead of only activating the on board buzzer.

Size of the module: 52 x 54 x 15 mm

Size of the display: 41 x 16 mm

Power supply: 3.5 – 5.5V, 50mA

The kit comes with a schematic on paper, but no manual. It is easy and fun to determine the function of the 2 push buttons.
