Description :


 

--Low RDS (on) output

--Automatic current decay mode detection/selection

--Mixed and slow current decay mode

--Low power dissipation synchronous rectification

--Internal UVLO

--Cross current protection

--3.3 and 5 V compatible logic power supplies

--Thermal shutdown circuit

--Ground short circuit protection

--Load short circuit protection

--Five optional step modes: Full, 1/2, 1/4, 1/8 and 1/16


 

--The maximum current is 2.5A.

--the highest support for 32 subdivisions.

--4 layer PCB board, better heat dissipation performance.

--the chip internal resistance is smaller, lower heat, better heat dissipation.

--Size: 1.5mmX2mm (same as 4988)

--Driven current: 2.5A

--Subdivision: 1, 1/2, 1/4, 1/8, 1/16, 1/32

--Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance

 

--ARM32-bit MCU control board, running faster, the maximum no-load speed reaches 40000mm/min, better algorithm optimization, less vibration when the machine moves at high speed, and more stable performance;

--X/Y/Z/A four-axis drive, Y-axis dual drive. Support for rotary axis

--The control board power supply and line number circuit use optocoupler isolation, the entire control board is safer, more stable, and has strong anti-interference ability

--External 300W/500W spindle

--Split design, control, drive and expansion boards can be replaced

--limit switches, 5V/12V/24V constant voltage pins

--Can be connected to a high-power driver

--Stepper drive subdivision adjustable

--Can connect 775 motor/3pin laser 4pin laser/offline controller. Reserve 24V, 12V, 5V power output ports to facilitate the expansion of various functions

--PWM/TTL software to adjust laser power

--Support USB flash firmware, firmware upgrade is more convenient
