Thanks @kale. I tried to get some second hand Axoloti but they are sold really fast.
Yes I know about Akso. Actually I have got one and just received it some days ago. Nevertheless I need an Axoloti because I was working on a very specific project and I have just ready the enclosure.
But when I started to mount everything together I found that my board has two damaged pins , so I need another Axoloti to replace it. Anyway it would be great to have some feedback about what can we expect about future batches.
In the mean time I will be attentive to future Axoloti used offers.
