New Break ThroughThe Rebirth of MINI E3SPECIFICATIONSize DiagramNote:

Regardless of the MCU used, the SKR MINI E3 V3.0 features the following: Integrated4 TMC2209 drivers (with UART interface),3 CNC fan ports, support 4 stepper motor drivers(X, Y, Z (dual Z-axis),E0),and 2 NTC ports. Additionally, it also provides the followinginterfaces: heated bed xl, heater cartridge x1, SD Card x1, Micro USB x1, LCD display x1.TFT display x1, auto power-off xl, power loss recovery x1, RGB x1, BLTouch x1,filament runout sensor x1, and X/Y/Z-axis limit switch x1. We will randomly shipthe SKR MINI E3 V3.0 equipped with either the STM32GOBORET6 or the STM32GOB1RET6
