5.Support onboard Sensorless homing function



BTT SKR MINI E3 V2.0 is a customized motherboard for Ender3 printer launched by the 3D printing team of BIGTREE technology co., LTD., which can perfectly replace the motherboard of the original Ender3 printer.

  • 1.Use MP1584EN power chip, support 12-24V power input, the maximum output current can reach 2.5A.
  • 2. The hot-bed MOS tube uses WSK220N04, low on-resistance, larger heat dissipation area and reduces heat generation.
  • 3.double Z-axis .
  • 4. Supports BLtouch, detection of blocked rotation, resumption of shutdown, shutdown after shutdown, etc.
  • ....


1. SKR V1.4 with 32-bit main frequency 100MHz ARM level Cortex-M3 series LPC1768 main control chip

2.SKR V1.4 Turbo with 32-bit main frequency 120MHz ARM level Cortex-M3 series LPC1769 main control chip

3.Support Resume Printing While Power Off, Filament Break Detection,Automatic Shutdown After Printing and so on.

4. I2C, SPI and WIFI interfaces are reserved for convenience of DIY.

5.Support RGB light bar



1.Two working modes of UART serial screen and 12864-like screen can be selected, with higher compatibility.

2.Serial screen mode supports two printing methods: SD card and U disk.

3.Reserve WIFI interface, support external WIFI module to realize WIFI function.

4. sets of UART serial expansion ports are reserved for user DIY up to 15 languages
