Product Introduction
BigTree Technology Co., Ltd. developed this high performance and customizable 3D
printer controller board to provide a direct replacement for the Ender 3 which has
more options.
Main Features
1)
The board is controlled by a STMicroelectronics ARM Cortex M3 32-bit
STM32F103RCT6 MCU. This chip has a Maximum Clock Frequency of 72 MHZ.
2)
Supports 2.8 inch, 3.5 inch color touch screen and original Ender3 printer
LCD12864 screen.
3)
Integrated UART TMC2209 stepper motor drivers.
4)
Supports open source firmware Marlin2.0. This means it is convenient for
users to customize their firmware and develop it. The firmware is upgraded
with a SD card, which is very convenient and efficient!
5)
Dedicated ports for BL Touch, stallguard, UART and SPI.
6)
High voltage input means heated bed current draw can be reduced to 1/4,
without power loss.
7)
Supports functions such as BL touch, RGB LED, stallguard, printing after power
failure and power off after print finished.
8)
The layout of the PCB is optimized for heat dissipation.

2)
Input voltage: 12V-24V DC
3)
Max. allowable total power usage: 180W@12V, 360W@24V
