3D printer control upgrade kit

This kit bundles a SKR Mini E3 V3.0 mainboard, a BTT Pi V1.2 compute module, a TFT35 SPI V2.1 touchscreen and an SFS V2.0 filament sensor. It targets owners of i3 or CoreXY machines such as Ender-3, Ender-3 V2 or Voron 2.4 who want to run Klipper firmware. All components are new and designed to work together out of the box.

Sustained thermal behaviour

The SKR Mini E3 V3.0 uses an STM32G0 series MCU and adds controllable cooling fans plus an upgraded driver heatsink to keep temperatures down during long prints. The BTT Pi V1.2 runs a quad-core 64-bit ARM Cortex-A53 at 1.5 GHz with 1 GB DDR3 memory, providing steady headroom for Klipper host duties over extended sessions.

Compatibility checklist

Verify your printer uses a supported i3 or CoreXY kinematic and that the existing wiring can accommodate the new mainboard layout. The touchscreen connects via FPC cable and XH2.54 terminals, so confirm your mounting points and cable routing allow those links. The filament sensor needs two signal outputs for runout and clog detection; ensure your firmware configuration can map them. Buyers needing a different form-factor mainboard or a non-Klipper ecosystem should look elsewhere.

Questions about this item

How much heat does the SKR Mini E3 V3.0 mainboard generate during long prints?

The board uses an STM32G0B1RET6 or STM32G0B0RET6 chip and adds controllable cooling fans plus an upgraded driver heatsink to keep temperatures down during extended printing sessions.

What existing printer hardware is required to install this upgrade kit?

The kit targets i3 and CoreXY machines such as Ender-3, Ender-3 V2 and Voron 2.4, and connects via FPC cable and XH2.54 terminals to the printer’s current frame, motors and hotend.

Will the TFT35 SPI V2.1 touchscreen work with my older 32-bit mainboard?

The display communicates over SPI for video and I2C for touch, linking to the SKR Mini E3 V3.0 through an FPC cable and XH2.54 terminals, so it is designed for this specific board.
