3D Printer A4988 2oz Module Stepper Motor Driver Reprap

Tips: 2oz means 2 oz process production. Measured: With the current of the heat sink 2A, it can work for a long time. Ideal for use with Mendel and Huxley machines.

The A4988 module has completed 2oz upgrade work. At present, the factory produces a second-generation product. Compared with the first-generation 1 oz copper process, this production uses 2 oz copper, which has good heat dissipation and strong current stability.

Performance upgrade: PCB copper process upgrade to 2oz (copper thickness 70um, the average is 35um), high copper content, of course, good thermal performance

Manufacturing process upgrade: SMT placement machine manufacturing, non-manual welding, higher yield, stable performance

**Features:
- Low RDS (ON) output
- Optional heatsink included
- Automatic current decay mode detection / selection
- Mixed with slow current decay modes
- Synchronous rectification for low power dissipation
- Internal UVLO
- Crossover-current protection
- 3.3 and 5 V compatible logic supply
- Thermal shutdown circuitry
- Ground fault protection
- Load short-circuit protection
- Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16

**Remarks:
Reprap single jet printer set requires: 4 A4988 modules.
Reprap dual nozzle printer set requires: 5 A4988 modules.
