Description
The DFRobot PCB Engineering Ruler - Mini is a compact, pocket-sized reference tool designed for electronics engineers, makers, and hobbyists. Fabricated from rigid glass fibre, it provides instant visual guidelines for component sizing, wiring, and hardware layout directly at your workbench.
Compact glass fibre build
Measuring 160 by 32 mm, this palm-sized ruler is constructed from durable glass fibre for lasting reliability. Its accurate scale and sturdy material make it a practical aid for PCB layout, drafting, and model making.
SMD component footprint references
The surface features standard package outlines for resistors (0402 to 2512), capacitors (0402 to F60), crystals (3213 to 49SMD), and power ICs including SOT23, SO8, and SOT223.
Via and screw hole design guides
Engineers can quickly check metric screw hole apertures from M2 to M6 alongside via design diameters spanning 0.3 mm to 1.5 mm.
Wire gauge and interface standards
Includes quick references for American Wire Gauge (8 to 28 AWG), silkscreen text size scales, and the DFRobot Gravity design definition standard.
