I bought it with my own money. I developed a core board myself a while ago. The project was urgent. I adjusted the board at home during the May Day holiday. One of the power-on reset signals was not adjusted correctly. I thought of buying someone else's board to measure it. I bought it but it hasn't arrived yet. I adjusted it. This board cannot be repaired within seven days without reason.

This small board has a very wide range of applications.

Where is the energy to do these?

The kids in the family are too young and my grandparents are too old, so I’m the only one left.

Please reply to this post and give it a thumbs up!

Hey, my child is just over 100 days old, I can relate to this, let’s hug and encourage each other.

Dear OP, why don’t you learn it yourself before selling?

I did it myself, I have a board in my hand, I am not a big shot

I just checked, has the price increased? I remember that I spent this much on my development board.

This is the price, this one is 484, you may buy 400? But to be honest, it is better to buy a development board with various interfaces than my core board, which is more cost-effective. My board is expensive and needs a separate baseboard.

Indeed, I took a look and mine is XC7Z020-2CLG400I. I wonder what the difference is between 400 and 484?

A little more pins, no other difference

I made a core board by myself, using a second-hand FPGA chip that cost me a few hundred yuan.

How many layers of the board, is the cost so low? I have a ten-layer board, which I invested in Huaqiu online. Five boards cost 1450. The welding cost is more expensive than the components. So this thing still needs to be sold in large quantities, otherwise it will definitely lose money.

I used a six-layer board. Jiali Chuang offered free PCB proofing, so I didn't spend any money on proofing. I also soldered the board myself, and the only cost was the cost of buying components.

I have made a six-layer board for a single DDR3, but I can't make a six-layer board for two DDR chips. I don't have enough skills.
