BIGTREETECH SKR 3 Control Board

Description

BIGTREETECH SKR 3 Control Board BIGTREETECH SKR 3 is a successor to the SKR 2 and has many new functions. This versatile 32-bit motherboard with powerful 480 Mhz ARM Cortex-M7 is suitable for most 3D printers and offers many interfaces and upgrade options compared to most built-in motherboards. The motherboard is compatible with Klipper and Marlin open-source firmware. 480Mhz ARM Cortex-M7 BIGTREETECH SKR 3 uses a 32-bit ARM Cortex-M7 series STM32H743VIT6 chip with a core frequency of 480MHz, providing enough performance to handle even the most demanding user interfaces while enabling stutter-free printing. DIY friendly BOOT0 facilitates DFU mode to flash firmware The upgraded thermistor input now requires no external module for P1000 A universal WiFi modular port allows the use of RRF firmware SKR 3 compared to SKR 2 and SKR 1.4 Mainboard SKR 3 SKR 2 SKR 1.4 Main chip STM32H743VIT6 STM32F407VGT6 LPC1768 Core frequency 480MHz 168MHz 100MHz Output current 5A 4A 3A CNC fan 3 (24V, 12V, 5V optional) 3 1 PC interface USB USB USB Firmware support Marlin, Klipper Marlin, RepRap Marlin Temperature sensor interface 1-way 100K NTC, 2-way 100K NTC, PT1000 optional TH0, TH1, TB, 3-Way 100K NTC (Thermistor) TH0, TH1, TB, 3-way 100K NTC (Thermistor) WiFi interface ESP-12S, ESP-07S, ESP32 ESP-12S, ESP-07S ESP-01S Reserved BOOT0 Yes no no Onboard EEPROM Yes no no Product Specifications Product size 110x85mm Installation size 102x76mm Processor ARM Cortex-M7 CPU STM32H743VIT6 EEPROM 24C32 32-Kbit Input voltage DC12V-DC24V Logic voltage DC 3.3V Firmware Marlin, Klipper WiFi interfaces ESP-12S, ESP-07S, ESP32 Fan interfaces 3 CNC fans, 2 normal fans,Optional CNC fan voltage Extension interfaces Servos, Probe, PS-ON, PWR-DET, Fil-DET, CAN FD Motor drivers TMC5160, TMC2209, TMC2225, TMC2226, TMC2208, TMC2130, ST820, LV8729, DRV8825, A4988, etc. Driver working modes SPI, UART, STEP/DIR Motor driver outputs X, Y, Z (Dual Z-axis), E0, E1, five-way Heating interface Heated bed (HB), heating cable (E0, E1) Temperature sensor interface 1-way 100K NTC, 2-way 100K NTC, PT1000 optional PC interface USB File format Gcode 3D printer setup XYZ, Delta, Kossel, Ultimaker, Corexy Recommended software Cura, Simplify3D, Pronterface, Repetier-host, Makerware Screen Serial touch screen, SPI touch screen, LCD display Package Includes: 1x SKR 3 Documents: Manual GitHub Firmware Related Products: CNC | 3D PRINTER PARTS
