3D printing integrated motherboard

This project includes an integrated motherboard + direct plug-in 4-in-1 driver. It is based on the schematic diagram of Ramps 1.6. It has not yet been verified. I am preparing for the postgraduate entrance examination in 24 days and have no time. This is for reference only.
Maybe it will be a long time before we continue to improve it and become a eunuch project.
The original version is drawn by AD, refer to attachment
##. The motherboard screenshot is
based on mksgenlv2.1. It has all the conventional interfaces, including EXP1 and 2 screen control interfaces; AUX-1 serial screen interface (similar to TTF); hot bed and extruder 1 and 2. …………

## Integrated driver screenshot

--The driver supports UART; keep MS1 selected, MS2 (solder jumper)
--tmc2209
---It's a thankless effort and it's not easy to solder. (I didn’t solder a bit, so I bought a few driver chips and replaced the drivers for the original UM2 motherboard. As a result, I burned out 2 drivers after replacing them in 5 places. The technology was not in place.)

Thanks to the open source platform for the reference and learning opportunities.
