Preliminary CR4NS200320C13 board (Ender-3 V3) support #27003
Conversation
as found in the Ender-3 V3 SE
Driver configuration and display pin-out must be verified, this board uses the GD32F303 RET6 SoC, it could be compatible with the STM32F103 as in other boards with the same SoC.

Seems that MS35774 driver is a clone of the TMC2208, **TMC_UART** configuration was found only for X, Y and Z drivers, so maybe E0 is working in TMC2208_STANDALONE mode.
Based on the disclosed board configuration, images and Creality's printer.cfg
It may be, although this is labeled as GD32F303... so if it follows the same numbering as STM32 the MCU is a Cortex-M4 instead of a Cortex-M3, so it may have a few more built-in ports and capabilites. In any case, it's very fast! 168 megahertz is fast enough to outrun even the bigger imperial cruisers. |

It is a Cortex-M4 at 120MHz https://www.gigadevice.com/product/mcu/arm-cortex-m4/gd32f303ret6 |
Aha! Probably can still outrun most tie fighters. |
Maybe even Tie interceptors and close to the USS Defiant. |

Creality published the sources for the Ender-3 V3 SE and the board pin file is there: https://github.com/CrealityOfficial/Ender-3V3-SE/blob/main/Marlin/src/pins/stm32f1/pins_CREALITY_V3_GD303.h |

@mriscoc any progress on updating the pins? I'm trying to compile marlin for my ender 3 V3 SE and would like to help fixing the pins if you haven't started it yet. I've started a PR to merge the Creality official repo configs into the latest marlin repo here I only noticed now that the board was already supported |
Hi, I don't have the printer to do the necessary test, it is not only a problem with pins, also the screen is different from other Ender 3 editions. But I think that I have a more updated board pin definition file here: mriscoc/Ender3V2S1@404e13a#diff-98d676e6f66dab4f9542d7a68843115ba18b0af88f410703c148c11b9525d27b |

@mriscoc, Thank you for your work. Hope some one test it and upstream this pins. |

if anyone is particularly keen these board are half off on aliexpress at present... |
