Feature

●【Cost-effective Combo Set】This set include BTT SKR 3 mainboard*1 and BTT TMC2209 V1.3*5, its a perfect combp set for bargain-hunters in 3D printers.
●【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.
●【Ultra Silent Stepper Motor Drivers】BIGTREETECH TMC2209 uart stepper motor driver adopts stealthChop2 Mute technology to reduce motor noise to the point of silence at low velocities, ensuring noiseless operation, maximum efficiency and best motor torque. SpreadCycle allows highly dynamic motion.
●【Excellent Heat dissipation and Lower Heat】Compare to other TMC2209 stepper motor driver in the market, BTT TMC2209 V1.3 stepper motor driver generates lower heat, it can lower 30% heat than others stepper motor drivers even keep working for a long time. And it has a larger cooling area to lower the temperature. With Passive cooling on a 10 hours print, they only hit 37°C.
