Light cube design based on STC15F2K60S2

Uses USB power supply and downloading. Using UL2803 chip driver. HC573 latch. This kind of chip can drive large capacitance or low impedance loads, and can directly interface with the system bus and drive the bus without the need for external interfaces. Each piece of the light cube is a separate facade. Electrically, there are 8 facades of L1- L8 is all connected horizontally, forming a common cathode connection. The 8 independent elevations C1-C8 are connected to pins 1-8 of the pin header P2 in sequence. C1-C8 of different elevations are connected to H1 in sequence. On the H8 pin header. The light cube lamp body has a common cathode connection. The positive poles of all LEDs in each vertical column are connected together. There are 64 vertical columns in total. The negative poles of all LEDs in each horizontal layer are connected together. There are 8 horizontal layers in total. . The outer shell is designed with Fusoin. Please wait for subsequent updates
