The usage strategy is conservative; the normal operating temperature is only slightly higher than room temperature (test room temperature 28℃).
The heat dissipation design meets the requirements of long-term load operation. During stalled operation
, the motor will momentarily output maximum power and then trigger chip protection. Even during long-term stalled operation, the motor temperature remains very low.
Extreme testing was not conducted. It should be able to operate within 1.8A

] Please refer to the manually edited table in the schematic for the component list. The BOM generated from the webpage may be inaccurate in some parts.
We recommend using solder paste and a heating plate for soldering.

**Choose either the forward or reverse resistor; soldering both will not control the connection.**
