SKR Mini E3 V2.0

Note: In the case, you get the SKR Mini E3 V2.0 with GD32F1 MCU instead of STM32F1 MCU, and might be facing a potential issue list here: USB MSC and CDC issue. Please do contact our support@cytron.io.

BIGTREETECH SKR MINI E3 V2.0 is a customized motherboard for the Ender-3/Ender-3 PRO printer launched by the 3D printing team of BIGTREE Technology co., LTD., which can perfectly replace the original motherboard of the printer.

Check out the review by Michael from Teaching Tech about the latest SKR Mini E2 V2.0:

BTT SKR MINI E3 V2.0 Features:

• Uses MP1584EN power chip, support 12-24V power input, the maximum output current can reach 2.5A
• The hotbed MOS tube uses WSK220N04, low on-resistance, larger heat dissipation area, and reduce heat generation
• Onboard Sensorless homing function, which can be used by plugging in the jump cap
• Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components
• Support BLTouch, filament detection, power-off resume, automatic shutdown, etc.
• Onboard EEPROM: AT24C32
• Add parallel double Z-axis interface
• Increase the board layer: 4 layer board
• Increase the heat dissipation area of the back driver and strengthen the heat dissipation capacity
• Two CNC fan interfaces
• Increase the distance between the driving chip and the components to avoid the trouble caused by the heat sink
• Add a protection device to the thermistor interface
• 5V power supply with BLtouch, TFT, and RGB interfaces is optional
• The driver shares a physical UART port, which saves IO and enhances stability
