Creality 3D Ender-3 S1 kit carte mère

The Creality Ender-3 S1 Mainboard Kit V4.0.1 is a direct replacement and upgrade control board engineered for the Ender-3 S1 series. Unlike generic 8-bit boards that produce audible stepper noise and lack modern connectivity, this 32-bit board runs an ARM Cortex-M4 core at 100 MHz, delivering smoother motion, faster processing, and near-silent operation thanks to integrated TMC2209 drivers in UART mode. It is the exact board used in the Ender-3 S1, S1 Pro, and S1 Plus, ensuring perfect fit and full firmware compatibility.

Highlights

• 32-bit STM32F401RET6 microcontroller with 512KB flash and 96KB RAM for responsive performance
• Integrated TMC2209 stepper drivers in UART mode for silent, precise motor control
• Dedicated CR Touch / BLTouch probe port for automatic bed leveling
• Pre-installed Marlin firmware and bootloader for plug-and-play installation
• Robust thermal runaway protection and multiple fan outputs for reliable printing

In daily use

Installing this mainboard transforms the printing experience. The silent stepper drivers eliminate the characteristic whine of older printers, making it suitable for home or office environments. The dedicated probe port simplifies adding automatic bed leveling, while the USB-C and SD card interfaces offer flexible file transfer. The board’s 24V input matches the S1 power supply, and the three fan ports allow independent control of hotend, part cooling, and mainboard cooling for optimal thermal management.
