I'm not quite sure I understand what you are saying I'm afraid.
Do you have a controller board for sale?
Yes. If I find one or more S5 blades to replace my broken half working S5 blade.
Obviously, it takes time to find one.
Are you interested in a trade: my S5 blades for one of your SP20E's plus payment?
Sorry, there seems to be a bit of a language barrier I think
I'm not very interested, because shipping SP20 is very difficult to arrive them not broken.
The last time I sent four miner at once in one large flat box. Each miner was wrapped in many layers bubble wrap.
All miners survived shipping.
Arrive in the original carton not broken, is only a 66% chance. I sent three miners in the original boxes. One has arrived broken .
SP20 shipping costs to you is 28EUR with omniva.
