2Pcs SMT SMD Component Welding Practice Board Rectifiers CD4017 NE555 Soldering Skill Training Board Flowing Water Light Kit DIY Electronic Kit Mini Practice Board Easy SMD

Key features

• The product is a loose part with a circuit board: the PCB circuit board is equipped with all components, and you need to assemble and debug it yourself
• The welding practice board for SMD components adopts double-sided components, and the double-sided SMD practice has a high board occupancy rate and good cost performance
• The circular circuit in the middle is a water lamp circuit, composed of CD4017, NE555, and light-emitting diodes. It can work after being powered on after welding without any errors
• The PCB circuit design is reasonable, without burrs, and is small in size, which can be packed in a pocket
• Three columns of components on the left and right are used for welding practice, and each column has test points
