BIGTREETECH Direct SKR 2 32Bit 3D Printer Silent Control Board + 5pcs TMC2209 V1.2 Stepper Motor Driver DIY Upgrade Ender 3 BIQU B1 3D Printer STM32F429VGT6 New Upgraded Version(SKR 2+5PCS TMC2209)

?Packing List?:SKR 2 Control Board + 5pcs TMC 2209 V1.2(with a cute duck), for more information,please search bigtreetech github SKR 2 motherboard is a 32 bit 3D printer motherboard , It is a successor to the bigtreetech SKR V1.3 SKR 1.4 and SKR V1.4 Turbo series of motherboards and adds many features that we are sure the community will love. ?More Features for SKR 2 32 bit 3d printer controller: 1.Uses a 32 bit ARM Cortex M4 series STM32F429VGT6 main control chip with a core frequency of 168MHz that packs enough performance to run even the most demanding UI while ensuring stutter free printing. 2. Integrates a AOZ1284PI power regulator which supports 12 24V power input and a maximum output current of 4A – enough to power external components such as LEDs and even a raspberry pi; 3.Support all versions of the company's serial screen, SPI screen and LCD screen;like TFT28,TFT35 V3.0,TFT35 E3 V3.0,TFT43 V3.0,TFT50 V3.0,TFT70 V3.0 and 12864 lcd ect 4.Support TMC2208 TMC2209 TMC2130 TMC2226 TMC5160 Stepper Motor Driver,TMC Motor drivers can be used in SPI or UART mode by simply adjusting the onboard jumpers beneath each motor driver. Additionally you can connect or disconnect the TMC DIAG pin using an onboard jumper allowing you to use hard endstops or sensorless homing without the need to cut any pins. 5.Supports functions such as power loss print resume, filament runout detection, shutdown after printing, BLtouch and other ABL sensors, RGB lights, etc. Note that external modules will be required for many of these functions; TMC2209 is an ultra silent motor driver IC for two phase stepper motors. Its continuous drive current is 2A and peak current is 2.8A. 2Voltage Range : 4.75V 28V Peak current:2.8A; Current RMS:2A; Microstep setting:24816(can be divided into 256parts)
