I ordered an OV2640 and received a GC2145 module. I do not recommend the seller or the product; it doesn't work and is useless. Bad purchase.
The product arrived within the expected delivery time (perhaps even earlier than the estimated delivery date on the website) and with adequate protective packaging. I have yet to test its functionality, but the product matches what was indicated in the advertisement and should not present any functional issues.
They work without problems, but it came with the wrong camera sensor... it didn't come with the OV2640.
Good
