3D Printer Parts Mute Motherboard TMC2208 Motor Drive Burn ET4 + Firmware Support Offline Upgrade Power-off Continue Printing Material Breakage Detection 8-35V for Anet ET4 - Black

Main Features:
Using 32-bit high-speed ARM chip as the main control chip STM32F407, the main frequency is up to 168MHz, compared with mega 2560 (16MHZ), the data processing ability is faster. The use of high-quality MOSFET tube, the heat dissipation effect is better.
Using a dedicated power supply, the chip supports 12-24V power input. The same system power supply can reduce the hot bed current to 1/4, which effectively solves the problem of MOS tube heating.
Industrial-grade chipset, more accurate and faster printing, with safety functions such as over-current protection, overload protection, over-temperature protection and over-temperature alarm.
(Automatically turn off the heating switch) Support offline upgrade function, copy the upgrade file to the memory card, insert the 3D printer to complete the program upgrade.
The TMC2208 motor driver chip is built into the motherboard and replaces the A4988. Ultra-quiet, low resonance, 256 micro-step subdivision, to achieve no noise, low jitter, no loss of step, and finer printing of stepper motors during operation.
It can directly replace the original motherboard of the new Anet ET4 model in 2020.
