Hello! IC2811 and IC1903 are common LED control chips, the two have the following differences:
1. Control mode: IC2811 adopts single-wire control mode, while IC1903 adopts dual-wire control mode. 2. Common occasions: IC2811 is often used in digital light strips, modules, etc., while IC1903 is often used in pixel lights, dot matrix screens, etc.
3. Data transfer rate: The data transfer rate of IC2811 is slightly slower than that of IC1903, at 800Kbps and 1.2Mbps. In general, IC2811 and IC1903 can achieve LED control, but in the specific application, you need to choose according to the actual situation.
ic2811 indicates 2811 ics, and ic1903 indicates 1603 ics.
