My recommendation is a bit different, instead of that, try looking for a local manufacturer and support them.
Here in Brazil, people go for the cheap aliexpress clones to the point where some of our own manufacturers are closing shop. In these cases, strengthening the local ecosystem might be interesting and wiser in the long run.
Why? Your manufacturers could focus on something more profitable. What's the point in making another Arduino like board? Supporting non innovative shops is not good in short and long run.
It is like China and the shanzai spirit, first you clone then and make it sustainable then you innovate... (this is my personal opinion, I may be wrong).
I believe that supporting local non innovative shops is better than having no local shops at all.
But this is a result of that country politics. You should rather press government to make it possible to compete with Chinese (by for example lowering taxes, lessening the amount of bureaucracy - I heard this is a nightmare in Brazil). Throwing money at economy that is full of flaws will just delay the agony and not solve anything.
There are many clones. Check out "mateduino"[2] which is made in the south of Brazil and also the one from robocore which is made in the southeast. There are others. The ones from robocore are great[1].
