3D printer control board SKR MINI E3V2_lite version

The latest 6-axis Klipper control board has been released:
3D printer klipper control board Mini E3S6 - Jialichuang EDA open source hardware platform (oshwhub.com)
 
This project follows the open source agreement, original project link: BIGTREETECH-SKR-mini-E3
 
Original project E3V2 principle The picture is as follows:
The modified schematic diagram is as follows:
Modification instructions for this project:
1. Change the motherboard integrated TMC2209 driver chip to a module row interface;
2. Simplify the power supply and change it to a single power supply, using SGM6132 to output 3A current, which can be directly used for Powered by the Raspberry Pi;
3. The TF card SPI interface is used to connect the ADXL3445 three-axis accelerometer;
4. The BOOT0 pin is led out;
5. Modify the MOSFET gate pull-down resistor position;
6. Modify the PCB size to adapt to Voron V0.1 The structure can be assembled directly behind the Z-axis.
 
Due to the professional version of EDA design, it currently does not support direct display of project drawings and BOM, and needs version 1.6 to support it.
The schematic PDF document, plate making Gerber file, and BOM are included in the attachment for download.
Use the MOSFET you already have on hand, please replace it as needed.
 
Except for the RGB light and TF card functions, this project has not been verified. All other functions have been verified using the actual installation of klipper firmware.
It is theoretically possible to install Marlin firmware but not verified.
Klipper firmware provides attachment download
