This plate is a glow clock core board, which integrates all functions of a glow tube clock, including a boost module. A complete 6 - bit glow clocks can be made as long as a plate is added to the glow tube. The switch machine is used by remote control. It also has an external infrared and power interface to facilitate users to make shells.The clock uses DS3231, built-in crystal oscillator, timing is more accurate. The boost part adopts the MAX1771 high efficiency scheme, and the heating is low (the inductor can contact for a long time). MCU STC15W408AS, with anti cathode poisoning procedures, delay shutdown, timer switch machine and other functions. Small size is convenient to make smaller shell. Distribution of all wire. The use of 9 V 12 V, 500MA or more power adapter, the interface is DC 5. 5 - 2.
