1、Using 32-bit 100M Cortex-M3 LPC 1768 main control chip, the performance is greatly improved. 2、The circuit board uses a high‑quality 4‑layer board, and has been specially optimized for better heat dissipation. 3、Adopt dedicated power chip, support 12V‑24V power input. Use 8825 as the motor drive, support 32 subdivision, performance far exceeds 4988, adopt SOP package, heat dissipation effect is better. 4、Support the highly modularized open-source firmware for Smoothieware, which is convenient for secondary development and avoids the worries of not being able to master the core code. 5、Support network function, can be directly connected to the network through the network cable, and remote control can be realized by using the browser. 6、Can be connected to the 12864 LCD or the touch screen for MKS TFT28 developed by the maker base. 7、The stepper motor current is set directly without worrying about damaging the drive or potentiometer when adjusting the current.
