power expansion board

Heated bed high-power expansion module, with unique snowflake heat sink design, has a great cooling effect. This high power module helps your 3D printer become even more powerful. The module can solve the current load problem when the heated bed power is too large. Under the normal heat dissipation, the module can be stable long-term when measured I (Max) = 30A. When using the module, the current should not exceed 30A.
