レビューの一部は自動翻訳されています。
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.
