Problem: I like the Arduino, I like all the arduino clones, I like the ATMEGA329P. But I hate how all PCB dev boards have these dinky female headers. Yes there are screw shields but that does not address the issue of a more, drop-in ready-to-go industiral-ish PCB the ATMEGA328 could benefit from. Furthuremore, I am always bothered by the puny DC regular on most Arduino Unos; the DC input was 6-9v on average. Why not 12V? I have soooo many 12DC adapters. Adding a beefy 5V regualtor is also on the list to address.
Background: It's been a while since I used Eagle CAD... Good reason to practice.
I needed some basis to build a list of features, so I focused on something that surpirsed me with its popularity- my Venduino. This PCB is a good drop-in to get the Venduino wired , but it's also an excellent basis for any microcontroller project. Stuff I tried to make as a 'feature' for this arduino-compatible board:

Parts Needed... The basics to build an Arduino Uno + screw terminals.

What can I use this PCB for? Lots of stuff, but in keeping the spirit of this site's videogame something realted, you can make a N64 controller testing station. Let me explain how this came about. I was very intruiged when this N64 controller tester video showed up in my Youtube feed. This is the same person who was able to reflash GB carts among other things (link goes to the github post). Thought it would be neat to have a PCB for this, but that wasnt enough reason to make a PCB. Fast foward a few months later and the Venduino gets all this attention. Why not make a PCB that shares both puposes.
