Product Features
Compatible with Marlin and Klipper
Drive and control integration Can run Marlin firmware alone or freelyrun Klipper firmware with Raspberry Pi
Main Control Chip
ARM Cortex-M4/STM32F401RET6
Onboard TMC2209`s UART Mode-Ultra Quiet Adjustable drive current via serial port for powerful output and effective noise reduction
Reliable Design,
Stable System Performance
Excellent Heat Dissipation
Independent cooling to enhance drive heat dissipation.
More Extended Function Interface
Support auto leveling, filament run-out detection, power resume, easy installation easy to DIY
1. Filament Sensor Port
2. Auto Levelling Port
Pay attention
1. Please ensure that the positive and negative poles of the power supply are correctly connected before powering on.
2. Please do not plug or unplug the motor when the power is on, so as not to damage the drive.
3. The motherboard is pre-flashed with the basic version of marlin firmware(Ender-3),which can be used directly. or you can download the open source code to compile the firmware as needed.
Firmware Update Instructions
1. First format the TF card.and create a new
"STM32F4_UPDATE" folder in the root directory,and download the firmware bin file to the folder:
2. lnsert the TF card into the TF card slot of the motherboard and power on it, wait for the system to start up(the display
screen is displayed normally)
*The motherboard information can be downloaded from our Github website:
