3D Printer A4988 2oz Module Stepper Motor Driver Reprap Tips: 2oz means 2oz process production. Measured: Under the current of 2A with heat sink, it can work for a long time. Very suitable for Mendel, Huxley machines. And the official Wiki product, 100% consistent! The A4988 module has completed the 2oz upgrade. At present, the factory produces the second-generation products. Compared with the first-generation 1oz copper process, this production uses 2oz copper, which has better heat dissipation and stronger current stability. Performance upgrade: PCB copper cladding process is upgraded to 2oz (copper thickness is 70um, common is 35um), the copper content is higher, and the heat dissipation performance is of course better Manufacturing process upgrade: SMT placement machine manufacturing, non-manual welding, higher yield and more stable performance ![](https://ae03.alicdn.com/kf/Sd7db068cb5b94707a0e4b16ac4a9cb12C.jpg) ![](https://ae03.alicdn.com/kf/Scccf07f4a7134abb8b016356a08b34d36.jpg)
