Product Description
Octopus V1.1 Control Board
Support Klipper firmware and Raspberry Pi online printing.
8 stepper motor 6 groups of limit switches 6 PWM fans, 2 always-on fans 4 hotend heaters 2 filament runout interfaces
BTT TMC2209 V1.2 Stepper Motor Driver
The kit contains 8pcs TMC2209 V1.2 drivers
Compared to the TMC2208, the drive current is improved by 0.6A–0.8A, while the Blockage increases the stall detection function.
Provides up to 256 segments;stallguard4TM stall detection, which can feed back an abnormal signal when the motor rotates abnormally.
The motor is not easy to lose step; ultra-quiet mode; A large area of thermal pad, reduce the temperature of the driving work; Coolstep current dynamic adjustment, saving 75% of energy. Prevent motor shake;Support stall detection;Support STEP / DIR and UART mode;
6 PWM controllable fans interface, 3 selectable fan voltage.
Support 8 stepper motor drivers.
Support CAN BUS, convenient for future expansion.
Thermistor input protection.

🐙【Main Control Chip】Uses a 32-bit ARM Cortex-M4 series STM32F446ZET6 main control chip with a core frequency of 180MHz.
🐙【Strong DIY Support】This motherboard supports up to 8 stepper drivers with 9 stepper driver outputs in total; And up to 6 PWM fans and 2 always-on fans with the ability to individually select the voltage rail that will drive each fan. Select from Vin, 12V or 5V.
🐙【Motherboard Expansion Function】Support BLTouch, locked-rotor detection, shutdown after printing, resume printing after power failure, CAN bus, U disk function, IIC expansion; at the same time reserved WIFI interface, PT100 thermistor interface (optional), dual Z-axis printer.
🐙【TMC2209 Driver Features】The TMC2209 stepper driver is not easy to lose steps and is in an ultra-quiet mode; the module has a large area of heat dissipation pad, which can reduce the temperature of the driver when it is working; the module supports three modes: STEP / DIR and UART.
🐙【TMC2209 Driver Mode】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.
