12″ Raspberry Pi, Arduino, and Electronics PCB Ruler V2.0

Description

A 12″ PCB ruler featuring the Raspberry PI 4 GPIO pin out, Arduino  pin outs, and commonly used electronic components all on one easy to use  reference! It’s a sleek ruler that’s about as unusual  as they come. It’s fabricated using tough FR-4 PCB material with a green or black solder mask. The copper has a gold plated finish.

Here’s what’s on the ruler:

Front side:

Pin outs of a few commonly used micro controllers and of course, a ruler.

• The Raspberry PI 4 GPIO
• Arduino Micro
• Arduino Nano
• Adafruit Metro Mini
• Teensy 4.0
• Graduations in centimeters and inches
• Half of the inch graduations are sixteenths and half are tenths

Back side:

An assortment of commonly used electronics references.

• PCB trace widths and ampacities
• Wire size
• Resistor color code and common resistor size footprints
• LED schematic symbol, pin out, and common footprints
• Tactile push button switch footprints
• Capacitor footprints and capacitance unit conversions
• Transistor schematic symbols, pin outs, and footprints
