I completed my first PCB. But I really knew nothing when I started. How do I get someone to review what I made and tell me if it can be created or if I have problems? It began as a copy from a PCB by HowToMechatronics, but I ended up completely revamping it (to use a Nano). I want to get it printed, but it needs a critical review first. Can anybody help? Also, I don't know how to publish it so people can review it. And once people tell me it looks okay, how do I get it created? 1. Did I route something wrong? I noticed that the original from HowToMechatronics did not route the GND lines. I didn't understand why, so I routed them. 2. Are any of the lines too close? 3. I intend to power it though the USB port on the Arduino Nano using a Cell phone battery pack. So, no switch...just unplug. P.S. This site ROCKS! Needs better learning tools and help information, but functionality of the site is excellent! P.P.S - I think I made the project public. [https://easyeda.com/jimkrug/arduino-radio-controller](https://easyeda.com/jimkrug/arduino-radio-controller) I want "Using Arduino Nano" reviewed. Feel free to review the other one, but GND is not routed and I don't know how it would work. Plus I think RobotDYN's board does not work properly with MISO and MOSI. I have 3 boards...none work. Nano worked on the first try.
