This module uses Taiwanese TTP223 chip with 7-second automatic reset and built-in LDO voltage regulator to ensure long-term stable work without crashing.

Benefits of using with 7 seconds automatic reset and built-in LDO voltage stabilization:

The reset function is also called the self-recovery function. The most important function is that some products, such as bracelets, mp3 and the like, require the power supply to be connected before the shell. If there is no reset, when the panel is buckled, it is equivalent to a finger touch, there will always be a signal output, which will cause the touch to lock. After the reset function, the touch signal will return to the initial state after the set time is exceeded, so that it can be used normally
The advantage of the built-in regulated LDO, it can work stably without an external LDO chip, saving space and cost. There is no built-in LDO regulated touch module, and the use of unclean power supply will cause power fluctuations, issue wrong instructions and cause crashes.
