Description

CD4017 Rotating LED SMD NE555 Soldering Practice Board

• It’s DIY Kits, Red Led. This is a perfect Soldering skills training materials for beginners.
• The back of the board with mm / Inch ruler, Easy to measure component.
• After welding, just connect electricity (3 – 12V) to see the effect.
• You can quickly judge the welding effect. The welding product is a beautiful water lamp circuit.
• High-quality PCB has clearly marked the electronics components, even beginners can easily solder successfully.
• Flow Water Lamp Circuit: CD4017, NE888, LED; after correct connection, it will operate.
• In the middle of the circular circuit for the water lamp circuit, by the CD4017, NE555, light-emitting diodes, welding power can work.
• PCB board design is reasonable, are commonly used in SMD components.
• The left and right of the three components are used to practice welding, each column with a test point.
• The circuit is also used on the back, a ruler to facilitate the measurement of components. There are examples of PCB conductors to facilitate the use of PCB design.
