CNC Shield Arduino Uno -- gt; https://www.tokopedia.com/avarelectric/cnc-shield-engraving-3d-printer-expansion-board-for-arduino-uno Official information: http://reprap.org/wiki/StepStick 100% compatible version. PCB gold plate Technology, exclusive production on the whole network! This production process has been improved again. This version is the third generation product upgrade! 3D Printer A4988 Module Stepper Motor Driver Reprap Tips: 2oz means 2 ounces of process production. Measured: It can work for a long time under the current with heat sink 2A. Ideal for use with Mendel and Huxley machines. 100% consistent with official wiki products! 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, the production uses 2oz copper, which has better heat dissipation and stronger current stability. Performance upgrade: PCB copper coating process upgrade to 2oz (copper thickness 70um, common 35um), higher copper content, better heat dissipation performance Manufacturing process upgrade: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance * Mohon Baca Catatan Pengiriman sebelum Membeli di https://www.tokopedia.com/avarelectric
