The Haitronic HS1073 motherboard consolidates the control functions of a 3D printer onto a single board, reducing connection issues that can arise when using Ramps1.4 interfaces together. It is compatible with the open-source Marlin firmware and uses the same configuration as Ramps1.4, which it can replace or connect to directly.
The four-layer board uses 4982 motor drivers in SOP packages for improved heat dissipation. It accepts a 12–24 V power supply and, with a 24 V input, reduces the heated bed current to one quarter of that in the same system, limiting heat buildup in its MOSFET.
