Drive is compatible with 99 percent of the market's plug-and-drive 3D printer motherboards such as SKR V1.3/SKR 1.4 Turbo, MKS GEN L V2.0, Anycubic I3 Mega board
BIQU TMC2209 V1.2 is an ultra-silent motor driver IC for two-phase stepper motors, it supports STEP/DIR and UART two working modes
TMC2209 run much cooler due to a large-area cooling pad which provides a current dynamic regulation technology that saves up to 75% of electrical energy
Adopts stealthChop2 ultra-quiet technology, it is quieter than any other driver like A4988, DRV8825, LV8729, Reducing the sound of your 3D printer considerably, even you can sleep right next to this printer at full speed without any disturbance
Potentiometer regulation instructions: First, rotate the potentiometer clockwise to reduce the Vref voltage. Second, rotate the potentiometer counterclockwise to increase the Vref voltage

The structure of the product is J-head hotend,thermistor,copper cap and heat tube
Applicable: For 1.75mm filament
12V 40W Hotend for Anycubic I3 Mega; 24V 40W for Anycubic ChironS
