on Aliexpress it is half the price of the FPGA alone on mouser
Aaand? What's your point?

it has hdmi and LCD panel interface

Read the OP.
That is either also on the cheap Gowin boards or available as breadboard-able add-ons. The FPGA used on the Tang Nano 9k already has the memory (SDRAM and PSRAM) integrated where the FPGA choosen by the OP does not so it needs external memory. Not that this is bad perse but it just shows that the OP's proposed board is pretty similar to the Tang Nano 9k. Audio output doesn't even include a codec. It is just PWM straight from an FPGA pin so basically a jack plug connected to a couple of FPGA pins. Not saying it can't work but for the OP's board to have better value compared to boards like the Tang Nano 9k, the added value needs to come from an ecosystem with ready to use building blocks and thouroughly tested examples.

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Read the OP.

it doesn't have the simple audio,  and only 2 button and 6 leds other than that is has everything else

Hello,

I has just finished the PCB board for this FPGA board. the PCB board has 6 layers and 141mm x 95 mm size.
Here are current schematics and PCB board:

I also attache a Gerber file. I am going to post this project as open-hardware on my Github account. I am also planning to make operating manual for this board and various tutorials related to soft-CPU implementation.

Regards

Hello,

I poured out cooper on all green (Ground) layer. I am attaching altered files with PCB and Gerber files.

Best regards
