Xiaobai’s first piece of UNO

Engineering Reference

    This project refers to the Arduino development board from Jiuzhi Qian Shuxi, https://oshwhub.com/yanranxiaoxi/Arduino-Uno-Development-Board-based-on-LGT8Fx8P-and-ATMEGAx8PB

Compared with the original project, some silk screen printing is added to make it more beautiful and more convenient to use.

    It is recommended to use Jiuzhi Qian Shuxi's engineering for board making. Since this version is wired by itself, there is a certain deviation in the distance between the measured power bus header and the analog input bus header, making it incompatible with the official shield board.

Silk screen adding location

    1. The jumper cap selected by VCC and the breathing light used in the first Arduino routine, and the power indicator light are displayed in reverse to enhance the daily use experience.

    2. The serial port, SPI interface, and IIC interface silk screen are added under the side header. Although it is a bit small, it can still be seen clearly.

    3. On the back, some silk screen printing was done in the style of the official board, as well as the LOGO of the sponsor JLC.

Silk screen marking on header

   I believe that friends who have used third-party UNO boards will feel that when plugging DuPont cables into the female headers, you need to carefully check whether the holes are inserted correctly. After adding pin headers, this problem becomes more obvious. At this time, I am very envious of the official board with silk screen. The pin header, and based on the inspiration from playing Gunpla before, I customized a version of water stickers, which is much more convenient to stick on the header.

    The picture above is a comparison with the official version of the silk screen printing. Except for the glossiness without ink, the rest is quite good. There is one female header that was not made because the original version did not have these female headers, so it was simply not made.

       The water sticker can be customized on Taobao . The link is 25 yuan + 10 yuan for shipping for A6 size. The price is about the same as the price of a domestic UNO. But if you customize it yourself, it’s fine. Just treat it as a device from Lichuang Mall with a big shipping fee.

       You can also add other patterns and use them as substitutes before color screen printing.

The sticker I received looks a bit light, but the actual effect is pretty good.         

     Note that when cutting the water sticker, try to be as big as your pattern because it is a whole piece of glue.

statement

        No one is allowed to use this project for commercial purposes. The Zhouyou LOGO is used to distinguish it from the official ARDUINO. It is only for your own entertainment use.
