Anet ET4PRO Mute Motherboard TMC2208 Motor-driven - Black

High-speed 32-bit ARM chip as the master chip STM32F407, clocked at up to 168MHz, in comparison with mega 2560 (16MHZ), faster data processing capability.
High quality of the MOSFET, a better cooling effect.

Using a dedicated power supply, power input chip supports 12-24V

The same system can supply current is reduced to 1/4 regenerator bed, effective solution to the problem of heat generation MOS transistor.

Industrial grade chipset, print more accurate, fast, with over-current protection, overload protection, over-temperature protection, over-temperature alarm and other security features. (Heating switch off automatically)

Support for offline update feature, copy the upgrade file to the memory card, insert 3D printer to complete the upgrade program.

TMC2208 motor driver chip built into the motherboard, substituted A4988. Ultra-quiet, low resonance, 256 micro-step breakdown, Stepper motor noise during operation, low jitter, without losing step.

Anet ET4PRO can directly replace existing motherboard (not available for ET4).
