Hello, friends!

I have card marked as SBC2440V4 (photo - https://imgur.com/a/0YX85JF ), box labelled as "FriendlyARM" and display also marked as "FriendlyARM 8.4"". Looks like it's Mini2440 clone?

I found descriptions and specifications - https://docs.ampnuts.ru/eevblog.docs/Em ... C2440I.pdf
I adopted linux kernel 2.6.32.2 from mini2440 and card works.

However, I can't find technical datasheet for this card. I need to know jumpers descriptions and GPIO pins descriptions.
Can anyone point me to technical datasheet?

Thank you.
