Module de commutateur tactile capacitif TTP223B avec capteur tactile numérique
Une partie de la critique a été traduite automatiquement.
Be careful. The power supply must be stabilized and the negative pole must be well grounded. 2.5 - 5 volts recomended. I burned 5 of them until I realized that my power supply was not grounded correctly. Vey good operation, very fast. It has 4 different modes, which are not explained here. There are 4 contucts that you can short them to select mode. The chip is TTP223B. Very good chip. See spect to understand the operation and the 4 different modes.
Le mien avait beaucoup de flux de soudure sur elle, mais aucun problème lors de son utilisation.
It's of good quality It has been successfully tested You can see the attached video for more details
buon prodotto per costare così poco, dimensioni molto ridotte
