PATIKIL Soldering Practice Board 1 Set Electronic Kit Prototype PCB Board DIY Welding Circuit Voice Controlled LED Light for Competition Experiments

Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Specifications: Product: Electronic production education kit; Applicable voltage: 4-12V; PCB board size: 65*27*1.6 mm; Effect: rotating water lamp; Package content: 1 set DIY electronic experiment education kit Advantages: 1. The voice control PCB board prototype kit is tin-plated, not easy to oxidize, high-strength fireproof, anti-drop material, can be repeatedly disassembled and assembled. After welding, you can check the effect by turning on the power. 2.Electronic components are clearly marked. There is a ruler on the back side of the circuit board for easy measurement. It can improve the welding skills of electronic professionals and hobbyists. Instructions: 1. Please make sure all components are in the correct orientation and position. Check if it is a pseudo/float weld. 2. Because the accessories are very small, we recommend using pointed clips to assist welding. Application: This voice-controlled soldering kit electronic practice board is a beginner's educational kit for those who want to improve their welding skills. The welded product is a beautiful water lamp circuit. Note: 1. Please check compatibility before purchasing. 2.Due to the luminous effect, it is normal for the product color to be different from the image.
