🌟【Superior Heat Dissipation Performance】New Upgraded SKR MINI E3 V3.0 main board is equipped with a large Aluminum heat sink of stepper motor driver instead of pieces small heat sink, this design is able to increase the heat dissipation performance of the motherboard by 20% which greatly strengthen the heat dissipation capacity of the driver totally.

☆【48V High Speed Printing】Motor voltage of SKR 3 EZ varies from 12V to 48V (need to use EZ5160 Pro driver for 48V) while SKR 3 varies from DC 12V to 24V. Higher voltage can extremely improve your printing speed and you can adjust it with a jumper cap. What's more, SKR 3 owns 2 normal fans, and the EZ version owns 3 normal fans, which can ensure the smooth operation of your printer and advance your printing quality.

☆【Safe Anti-misplugging Design】Wrong installation of drivers will not only cause damage to the drivers itself but even ruin the motherboard or catch fire. And according to our survey, 40% Users may misplug the drivers unintentionally. Our new arrivals SKR 3 EZ motherboard and EZ series drivers, featuring an unprecedented anti-misplugging design, can totally remove such hidden dangers to offer you a better and safer printing experience! (Traditional TMC drivers is still compatible.)

☆【Updates of Processor】The new processor of SKR 3 EZ controller is upgraded to 32-bit 480MHz ARM Cortex-M7 series STM32H743VI, with which the running speed and printing accuracy of SKR 3 controller is greatly increased by 30%+ while its working noise become lower. Its upgraded thermistor supports PT1000, exempting the need of external module.

🍀【New Upgrade of SKR 2】BIGTREETECH SKR 3 mainboard is the upgrade version of SKR 2. Its processor is upgraded to 32-bit 550MHz ARM Cortex-M7 series STM32H723VGT6.The running speed and printing accuracy of SKR 3 controller is greatly increased by 30%+ while its working noise become lower.

🍀【Robust Power System】SKR 3 controller board is equipped with TPS5450-5A power chip, which supports power input of DC12/24V and output current of 5A (peak output 6A ). With its robust power system, SKR 3 motherboard can firmly will be the perfect supporter for your Raspberry PI.

🍀【DIY Friendly Interfaces】BOOT0 is added for programming firmware in DFU mode. WIFI module (ESP-12S, ESP-07S, ESP32) enables you to easily debug RRF. SKR 3 motherboard also supports bltouch, resume printing function, RGB lights, blocking detection and shutdown after printing function. What’s more, it’s also compatible with TFT35 E3 V3.0/TFT35 V3.0/TFT28 V3.0/12864 LCD display as well as TMC2209, TMC2208, TMC5150, DRV8825 stepper motor drivers.

⭐SUPER PERFORMANCE CHIP: BIGTREETECH Octopus control adopts 32-bit ARM-level Cortex-M4 series STM32F446ZET6 chip with a frequency of up to 180MHz, and supports 8 stepper motors. Equipped with highly modular open source firmware Marlin2.0, which greatly improves the overall performance of the motherboard, and all the functions of the motherboard do not require any expansion modules, and supports running Klipper and Marlin firmware

⭐SUPER MULTI-FUNCTION CONTROL PANEL: Support material interruption detection, continuous printing after power failure, shutdown after printing, BL_Touch, support online printing, etc. Upgrading the configuration firmware through the SD card, the operation is simple, convenient and efficient. Using high-performance MOSFET, the heat dissipation effect is better.

⭐MULTI-FUNCTION DISPLAY: TFT35 E3 V3.0.1 touch screen has higher compatibility. You can choose two working modes: UART serial screen mode and 12864 screen mode. The WIFI port is reserved, and the WIFI function is implemented by an external WIFI module.SD card update firmware is simple and convenient, download from our github, copy and save to SD card

💡【Klipper Pre-installed】BIGTREETECH Pad 7 klipper screen is pre-installed with klipper firmware whose precision-oriented algorithms will improve printing speed by 2-5x. Equipped ADXL345 module and klipper’s input shaper function allows BIGTREETECH Pad7 to keep great printing quality in higher printing speed by mitigating vibration. BTT Pad 7 also supports intuitive G-code model preview.

💡【Strong Computing Power】BTT Pad7 combines the function of CB1, CB1 heatsink, Pi4B and a 7 inches IPS touch screen and can replace PI to run klipper. It is powered by CB1 V2.2, a 64-bit 1.5GHz core board with Allwinner H616 ARM Cortex-A53 processor to provide a powerful computing platform. The pre-installed CB1 is detachable and you can upgrade it to CB1 eMMC for larger ROM.
