DFRobot PCB Engineering Ruler, 160 x 32mm, Fibreglass

The DFRobot PCB Engineering Ruler is a compact and practical tool designed for electronic engineers. It is only the size of a palm, making it delicate, compact, and easy to carry. This engineering ruler provides quick references for PCB design, helping to improve work efficiency. It is an essential auxiliary tool for DFRobot engineers, and also a great help for ruler drawing and model making thanks to its precise scale and hard glass fibre material.

The ruler includes a variety of design references printed on its surface: wire diameter reference (AWG), via design reference (in mm), screw hole aperture design reference (M2–M6), resistor package sizes, capacitor package sizes, power IC packages, and crystal package sizes. The dimensions are 160 x 32mm.
