What customers say
This SainSmart board offers a compelling value for budget minded 3D printer builders, powered by an Atmega1284p chip suitable for many RepRap projects. While the attractive price is a significant draw, potential buyers should be aware of reported reliability concerns. Some users have experienced issues with component quality or unexpected failures, indicating a need for careful inspection and possible component replacement for long term stability. This board is therefore best suited for experienced hobbyists comfortable with troubleshooting rather than beginners seeking a simple plug and play solution.
