1、Board size: 80*60MM

2、Board thickness: 1.6mm

3、Board material: international standard plate, pads all tinned, fireproof and anti-drop material, can be repeatedly disassembled.

4、Net weight: 24g

5、PCB board design is reasonable, no burrs, size 60*80MM, can be put in the pocket.

6、The components used are commonly used SMD components.

7、The 3 columns of components on the left and right are for practicing soldering, each column comes with test points.

8、The middle round circuit is a running light circuit, consisting of CD4017, NE555 and light emitting diode.

9, the back of the circuit is also utilised to provide back components, double-sided SMD practice, the board occupancy is high.
