Electronic DIY Engineering Kit Touch Stepless Dimming Soldering Skills Practice

SPECIFICATIONSBrand Name: NONEChoice: yesCondition: NewHigh-concerned chemical: NoneOrigin: Mainland ChinaSupply Voltage: 5vType: diyWhen the light is turned on next time, the light brightness will rise smoothly to the memorized brightness to avoid sudden strong light irritation to the eyes.5. By short pressing (less than 0.5 seconds) the touch button, you can easily turn the light on and off.When the light is turned on, long pressing the touch button will start the stepless dimming function, and the brightness can be adjusted freely. After the dimming is completed, the chip will automatically memorize the selected brightness.1. The lamp is made of ceramic material and is easy to break. Handle it with care during welding and assembly to avoid damage to the lamp. Solder the lamp last.2. The short pin of the lamp is positive and the long pin is negative.3. The short pin of the electrolytic capacitor is negative and the long pin is positive.3. Input voltage DC5V.4. Solder the touch chip SGL8022W. The small dot mark on the chip corresponds to the small dot printed on the PCB.
