Elektronikos rinkinys: SMD praktikos rinkinys su LED indikacija

1. Board size: 90*60MM
2. Thickness of the board: 1.6mm
3. Board material: international standard plate, all pads are tinned, high-strength fireproof and anti-drop material, can be disassembled repeatedly.
4. The PCB board design is reasonable, and the commonly used chip components are used.
5. The three columns of left and right components are used to practice welding, and each column has a test point.
6. The circular circuit in the middle is a water lamp circuit, which is composed of CD4017, NE555, and light-emitting diodes. It can work after power-on after welding without error.
7. The back of the circuit is also used, with a ruler, which is convenient for measuring components. There are examples of PCB wires to facilitate PCB design and use.
8. Circuit working voltage 3~12V
9. This kit contains all the components in the following photos.

DĖMESIO. Parduodamas ne surinktas modulis, o komponentų (įskaitant PCB) komplektas.
