Feature

Signal Time-Series Signal

Module Principle

The colored LED lamp bead has a lamp controller directly built-in, in addition to the 3-color LED. This is called the IC lamp bead. You only need to input a 24-bit RGB control signal, and it will automatically generate a drive pwm signal internally. It also has built-in signal forwarding. For continuous input signals, after intercepting the first 24 bits, the following data is automatically forwarded from the DOUT port to the next lamp bead.
