Powered by DC 5V, it features a running water lamp LED that visually confirms successful soldering. With a clearly labeled PCB and comprehensive instructions, it’s perfect for millennials eager to master electronics or teach the next generation. Backed by responsive customer support, this kit transforms learning into an engaging, professional-grade experience. ## Description Working principle: Since the voltage across capacitors C1-C9 cannot change abruptly when powered on, the 2nd pin of NE555 is at a low level, and the 3rd pin of the output terminal is at a high level. The current is charged to C1-C9 through R61-R70 and RP1-PR5. When the voltage to 2/3 of power voltage, the level of pin 3 of the output terminal changes from high to low, the internal discharge of NE555 is turned on, and the capacitors C1-C9 are discharged through pin 7 of NE555, until the voltage across C1-C9 is lower than 1/3 of the power voltage, the level of pin 3 of NE555 changes from low level to high level, and C1-C9 is charged again, thus forming a circular oscillation. Changing the size of RP1-RP5 can change the output frequency of the oscillator. The NE555 clock oscillation signal is continuously added to the 14 pin of the 4017. There are 10 transistors connected to the output terminals of the 4017, which to drive the 10 LEDs. Under the action of the clock signal, a high level is generated in turn, then L1-L10 are lit in sequence, forming the effect of a running water lamp. After the SMD components are soldered, power on to form a running water lamp to detect the effect of the soldering ## Features - 【SMD/SMT Components Soldering Practice Board】: Input voltage: DC5V. The positive pole is connected to +, and the negative pole is connected to -. After the SMD components are soldered, power on to form a running water lamp to detect the effect of the soldering. - 【Before Soldering】: Some SMD components are relatively small, be careful not to lose them. The side of the diode with the green dot is the negative electrode. This electronic soldering kit is not a finished product, it need to be soldered by yourself. Please refer to the English instructions include in the package. If you have any questions, please contact us first for professional help. - 【Great Soldering Science Project】: This soldering DIY kit help you understand the basics of working with printed circuit boards and become familiar with a variety of electronic components, and practice soldering skills enjoyably for you and your kids, or students, or DIYers. - 【Easy to Assemble】: The connection that was clearly mapped and labeled on the board makes it easy to assemble. And you can refer the marks on PCB board to soldering each component. If it can't work after soldering, please contact us for support. - 【Perfect After-Sale Service】: Please read the User Manual before installing. Our policy is to make our customers happy. If you are not 100% satisfied, just contact our customer service, we will refund your money. ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 12.07 x 6.99 x 2.54 cm; 32 g | | Manufacturer recommended age | 12 years and up | | Item model number | SMD Soldering Kit | | Educational Objective(s) | Soldering Skills, Electronic Components Understanding | | Assembly Required | Yes | | Batteries Required? | No | | Batteries included? | No | | tech_spec_battery_description_toys | Alkaline | | Material Type(s) | Plastic Metal | | ASIN | B09YQDF942 | ## Product Details - **Brand:** Ovenot - **Theme:** Electronics - **Age range (description):** Adult - **Item dimensions L x W x H:** 12.1 x 7 x 2.5 centimetres - **Item weight:** 0.03 Kilograms ## Images ![Dingdong Store SMD/SMT Components Soldering Practice Board Electronic Project Kits DIY Soldering Kit Skill Training Board Led Transistor Set with Battery Case - Image 1](https://m.media-amazon.com/images/I/71q4O39PZlL.jpg) ## Frequently Bought Together - SMD/SMT Components Soldering Practice Board Electronic Project Kits DIY Soldering Kit Skill Training Board Led Transistor SMD Soldering Kit SMD Soldering Kit - Gikfun DIY SMD/SMT Components Practice Board Soldering Skill Training Kit AE1173 - Gikfun DIY SMD SMT Welding Practice Soldering Skill Training Board Ek7028 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/526144429-dingdong-store-smd-smt-components-soldering-practice-board-electronic-project](https://www.desertcart.ph/products/526144429-dingdong-store-smd-smt-components-soldering-practice-board-electronic-project) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-22*
