If you’ve ever tried to make a footprint in Eagle with more than one GND, VCC, VDD, NC, etc., pin, you might have noticed that you can’t have two pins with the same names, and you ended up having to name all your GND pins GND1, GND2, GND3, etc. If you’re mildly OCD like me, this is irksome, but thankfully there’s an easy workaround to this in Eagle. When defining your schematic symbol and naming each pin, rather than naming pins GND1 take the common name that you want to appear in your schematics and append it with @n. For example. [email protected], [email protected], [email protected] This ensures that each pin has a unique name, but they will all render as GND when placed on your schematic. Read on to see an image of the the schematic symbol defined for the power pins above (an LPC4350 for the overly curious).
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
