Based on the original SKR 1.3 board from BigTreeTech, the SKR Mini E3 control board is a drop-in upgrade for the Ender-3, Ender-5 and Pro models. It features a blazing fast 32 bit processor, integrated TMC 2209 Trinamic silent stepper drivers and plenty of extra features for convenience.
Using the same form factor as the stock Creality board, the SKR Mini E3 is a direct swap installation. Just plug the original connectors in to the new board and power it on to get started.
It comes pre-loaded with the latest Marlin 2.0 open source firmware ready to use, or load your own customized version right from the SD card. No burning a bootloader or flashing firmware over USB, the process is entirely automated.
Factory firmware is built for the Ender-3 and Ender-3 Pro. For use on the Ender-5 series 3D Printers, flashing the firmware is required.
SKR Mini E3 V1.2 Features
The SKR Mini E3 V1.2 control board offers massive improvements in terms of both hardware and features.
32 Bit ARM Cortex Processor
In contrast to the basic 8-bit Melzi board found on the stock Ender-3, this 32 bit ARM Cortex processor is capable of handling thousands of calculations per second. This means faster, more reliable 3D printing without missing steps or losing acceleration on curves.
Integrated TMC 2209 Silent Stepper Drivers
The latest Trinamic TMC 2209 silent stepper drivers are integrated on the board in a UART configuration. Using the latest StealthChop2™ and SpreadCycle™ technologies, they can be ran in quiet mode at less than 10db, or performance mode.
The TMC 2209 drivers aren't just silent, they are far more efficient than traditional A4988 drivers. They run cooler during use, capable of up to 256 microsteps, and support sensorless homing.
The popular BLTouch auto bed leveling sensors are supported out of the box. No need to buy a separate PIN 27 board, the SERVO and PROBE ports are included on the board for a quick and simple installation.
The Adafruit brand of individually addressable LEDs, NeoPixels come in all shapes and sizes from strips to rings. The SKR Mini E3 offers native support, acting as the microcontroller to power and manage a variety of different lighting solutions.
