3D Printer A4988 2oz Module Stepper Motor Driver Reprap
Tips: 2oz means 2 ounces of process production. Measurements: Under the current with radiator 2A, it can work for a long time. It is very suitable for Mendel and Huxley machines. With the official Wiki products, 100% consistent!
A4988 module has completed 2oz upgrade. At present, the factory produces the second generation products. Compared with the first generation using 1oz copper process, this production uses 2oz copper, which has better heat dissipation and stronger current stability.
Performance upgrade: PCB copper cladding process upgraded to 2oz (copper thickness 70um, ordinary 35um), higher copper content, of course, better heat dissipation performance.
Manufacturing process upgrade: SMT patch machine manufacturing, non-manual welding, higher yield, more stable performance
Remarks:
Reprap single nozzle printer set needs four A4988 modules.
A reprap dual nozzle printer set needs five A4988 modules.

A4988 adopts surface mounted QFN package (ES), size is 5 mm *5 mm, nominal overall package height is 0.90 mm, and with exposed heat sink to dissipate heat. The package is a lead-free package (suffix T), with 100 fog tin plated pin frame.
