40PIN screen adapter board

Universal dot screen PCB design - Easy EDA open source hardware platform (oshwhub.com) This is a universal dot screen board made before. The resistor array is a bit large, and the screen spacing categories are small. That's why we have this new project.
This is the explanatory video of this adapter board: [Open Source PCB] 40PIN screen adapter board sharing_bilibili_bilibili
Features of this adapter board: Each PIN can be grounded with a 0 ohm resistor and connected to VCC, or it can be used Other resistors and capacitors can achieve other effects (0603 package). At the same time, it is possible to realize connecting devices between two adjacent PINs, especially the capacitors often found in OLED screens.
Special attention should be paid to the fact that VCC and GND are not lead out at a single place, so they still need to be connected at the original screen location.
The screen adapter board introduces two arrangements of pin headers. The first is the odd-even pin header. This is very common and can greatly reduce the length, but it is not very friendly for screen testing, so I also introduced the sequential pin header. Needles are distributed sequentially on the left and right sides. Especially for testing parallel port screens, it is relatively friendly.
In addition, the double-row pin header can be connected to the previous generation universal dot panel for use.
 
Things that can be expanded and improved:
1. This is indeed a simple adapter board. It has less microcontroller than the previous one, so it still needs Dupont wire to connect.
2. Click on OLED, and often encounter 9V voltage. This board is not designed. If you want it in order, you can add one by yourself.
3. This board considers the situation of the FPC seat and increases the spacing between the two rows of pads, but does not reserve fixed pads for the FPC seat.
4. VCC and GND are not drawn out, and the 3.3V column is not considered. At this point, I think the screen generally only needs one voltage.
