stock per 3 april = 25 pcs

The module is a capacitive touch -type touch switch module based on the touch
detection IC (TTP223B) . In the normal state, the module output is low, the mode
is low power mode; when touching the corresponding position with the finger, the
module will output high level, the mode switch to fast mode; when 12 seconds
without touch, the mode and switch to low Power mode. You can install the module
