klipper oled screen adapter board

Introduction: The useless klipperOLED small screen has been verified on mks Monster 8. In theory, it can be used on all mks motherboards.

It's just for fun, it's poorly made, not very useful, the pictures are nice,
klipper doesn't seem to be able to mount the SD card through spi, it seems (does anyone know?)

LOBSTER-3D printed motherboard

Introduction: Low-cost 3D printing motherboard based on STM32F103C6T6, only supports KLIPPER firmware

This project is redesigned for the APK2.1 motherboard. Thanks to the original author for open source.
Compared with the original version, it adds optocoupler/MOS isolation and anti-reverse connection protection.
The main control uses STM32F103C6T6, the price is extremely low, and the pins are compatible with C8T6 and F303 series.
5v uses ry9320/8310. The power supply solution is small in size, simple in peripherals and low in cost.
The me6118 provides a 3.3v power supply, which is a perfect replacement for the 1117
motor driver and provides a separate power supply to improve stability.
The expansion board interface is replaced with an XT30+PH2.0 cable arrangement. Loading capacity and stability
The motherboard provides three temperature probes (one is onboard thermal), four controllable fans, and one lighting interface.
The expansion board will support 8-axis printers and is suitable for voron2.4 printers.
Expansion board link: LOBSTER -3D printing motherboard - eight-axis expansion board - Jialichuang EDA open source hardware platform (oshwhub.com)
Chinese name is "Lobster".
The auxiliary welding file
github link is provided in the attachment: github.com/XMU-ZC/LOBSTER
——— ————————
The motherboard is currently the first version of the test board. Although it has been checked several times, there is still a possibility of design defects.
It is only for those who are interested in trying it out. If the test board is damaged due to possible circuit defects, please be responsible for it.
Friends who are willing to take the trouble should wait for the official version of the motherboard to be released .
