OrangePi has shared purchase links for both AliExpress and Amazon, though only AliExpress currently has the board in stock. The OrangePi 4A is priced at $35.00 for the 2GB RAM model and $40.00 for the 4GB RAM variant.
Links in the article. The 4 GB was 50€ instead, but at least the ballpark is that way.
All fun but no USB 3.0. Doesn’t make any sense. Even a NanoPi M4 from August 2018 had USB 3 and PCIe. That board was really head of it’s time for the price.
I think that’s a misprint. Looks like two of the ports are 3 and two of them are 2.
Hmm doesn’t look like it: http://www.orangepi.org/img/4a/detail/23.png
Here’s where I found it https://a.co/d/0lh60eR but Amazon could be wrong too
On that link I only see USB 2.0:
USB 1USB Type-A 2.0; 3USB Type-A 2.0 HOST; 1*USB 2.0 HOST, reserved for customer expansion
