32 BIT MICROPROCESSOR: Built in ESP32 DOWD V3 chip, for Xtensa dual core 32 bit LX6 microprocessor, supporting clock frequency up to 240MHz.
POWERFUL AND VERSATILE: The main board adopt ESP32 WROOM 32U module, embedded dual core 32 bit high speed MCU, the clock is up to 240MHz. And integrate , Bluetooth module, update firmware through USB, can connect and web page to control printing.
SUPPORT VARIOUS SCREEN: This is a 3D printer main control board with onboard ESP32 , supports for Marlin2.0 firmware, in addition to ordinary LCD2004, 12864 screen, also supports for MKS MINI12864V3, and for MKSTFT serial screen.
8M BYTE CHIP: In addition, the module has a built in 8M byte Flash memory chip, which provides effective for more application scenarios.
BACK EMF : VEXP has designed a circuit for the back EMF generated by the stepper motor, which greatly reduces the damage to the motor driver.
