Litake UNO R3 Board for Arduino Compatible + CNC V3 Shield 4x DRV8825 Driver | Инструменты

Description:

Item type:tool

(1) UNO R3 CH340:
Add two rows of the holes for the pins. So it can be connected with normal Dubond line.
Add 3 rows of the holes for wiring.
Change the in-line package of ATMEGA328P to flat package.
CH340G Replace ATmega16U2

UNO for Arduino expansion board
EN ( stepper motor driver enable , active low )
Z.DIR (Z -axis direction control )
Y.DIR (Y -axis direction control )
X.DIR (X -axis direction control )
Z.STEP (Z -axis stepper control )
Y.STEP (Y -axis stepper control )
X.STEP (X -axis stepper control )
(3) DRV8825
1)Simple step and direction control interface
2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
3)Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
4)45 V maximum supply voltage
5)Built-in regulator (no external logic voltage supply needed)
6)Can interface directly with 3.3 V and 5 V systems
7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
8)Short-to-ground and shorted-load protection
9)4-layer, 2 oz copper PCB for improved heat dissipation
10)Exposed solderable ground pad below the driver IC on the bottom of the PCB
11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
