I would like to have a pinout chart for the mainboard used in the SOVOL SV04. Does anyone know where it can be found?

No pinout chart, so far… but there is some information available, that might help:

- the circuit wiring scheme on page 35 of SV04 guide document that came with the SD-card
- the datasheet of the GD32F303VET6 MCU used on the mainboard contains its pinout. It can be found here: [https://gd32mcu.com/download/down/document\_id/240/path\_type/1](https://gd32mcu.com/download/down/document_id/240/path_type/1)
- alternatively, if your mainboard has a STM32F103VET6 MCU, the datasheet is available here: [https://www.st.com/resource/en/datasheet/stm32f103ve.pdf](https://www.st.com/resource/en/datasheet/stm32f103ve.pdf)
- the GPIO pins used for SV04 could be derived from the file “pins\_CREALITY\_V4.h” provided in Sovol’s Github repository here: [https://github.com/Sovol3d/SV04-IDEX-3D-Printer-Mainboard-Source-code](https://github.com/Sovol3d/SV04-IDEX-3D-Printer-Mainboard-Source-code)

Recently jbu313mlb92ome8w [added some more useful information about the SV04 pinout on GitHub.](https://github.com/jbu313mlb92ome8w/SV04)

I was able to get a BTT TFT35 working on the display port (P1): 5V NC TX(PB10) RX(PB11) NC GND

very beta Marlin 2.1.x: [GitHub - secabstraction/Marlin at 2.1.x\_SV04\_Creality521\_BTT\_TFT35V3](https://github.com/secabstraction/Marlin/tree/2.1.x_SV04_Creality521_BTT_TFT35V3)

Ok with marlin 2.0 not ?  
Tft35 btt should work with marlin 2.x ?  
Is the marlin mode working and the touch with 2.1 beta ?
