Комментарии об отличиях

WS2801 ↔ SM16716

WS2801 — SOP-8, 3-ch LED driver, SPI interface (CLK/DATA), constant current output, external resistor programmed, 8-bit PWM per channel. SM16716 — SOP-16, 3-ch constant current driver, double-line self-reshaping data transmission (NOT SPI), built-in LDO (VDD 3.3-6V), 256 gray level (8-bit), max clock 30MHz, constant current up to 60mA, OUT withstand 26V. КРИТИЧЕСКИЕ ОТЛИЧИЯ: SM16716 имеет другой протокол (не SPI, а proprietary serial), другой корпус (SOP-16 vs SOP-8), и built-in LDO. НЕ pin-to-pin замена — требуется редизайн PCB и новый firmware.
