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
- alternatively, if your mainboard has a STM32F103VET6 MCU, the datasheet is available here: 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
