Notice the swap of pins 2 and 8. If you layout a board using the public sheet, you will short your negative supply to ground. The exclusive sheet marks this difference in red ink and provides a verified breakout board footprint.
The MY-9892 is a 2000W, 10A SCR voltage regulator and PWM dimmer switch module designed for controlling AC loads, such as motor speeds and heating elements. Utilizing a BTA16-600B triac and a 500 KΩ potentiometer, the device offers adjustable voltage output from 50V to 220V AC with integrated heat management.

The exposed thermal pad must have 9 vias (not 4, not 16) of 0.3 mm diameter, filled with non-conductive epoxy. Too many vias wick away solder; too few cause thermal shutdown at 100 mA. Notice the swap of pins 2 and 8
Standard builds use a BTA16-600B or BT136-600E SCR/Triac capable of handling high voltage spikes (up to 1200V). The MY-9892 is a 2000W, 10A SCR voltage
As I poured over the datasheet, I discovered some interesting features that aren't immediately apparent. For example:
