美国采购需求：配件、控制卡

I'm reaching out to check if you have the older version of the LED card with the specific 50-pin connectors that I'm looking for. It's crucial that this version is not the newer model that has the smaller connectors. I need to ensure compatibility with our existing setup, which relies on this older configuration. If you do have this older LED card in stock, could you provide some details on its availability? Also, I would appreciate any information regarding pricing and lead times for potential orders. Looking forward to your prompt response so we can move forward quickly.
