This is one sweet board, so sweet we carry two versions of it. The Octopus Pro has been boosted to 60V! Perfect for an all out, or future proof build.
The key difference between the 446 and the 429 variant is the 429 has an upgraded board (SMT32F429ZGT6) with 1M memory vs 512K with the 446.

Flexible controller for every situation
I purchased this board for my first build and it was so excellent that I purchased a second. I use it in a 48V setup and it's got more than enough outputs for everything I need. The flexibility of being able to choose your voltage for steppers is a more flexible option than some other boards like the Kraken. This board exceeded my expectations.
