PACK 3D PRINTER - UNO R3 + CNC Shield V3 Expansion Board + 4pcs DRV8825 Stepper Motor Driver

DEVELOPMENT BOARD (CH340) + CNC Shield V3 Expansion Board + 4pcs DRV8825 Stepper Motor Driver Module for 3D Printer

CNC Shield Board:
1>PWM Spindle and direction pins
2>2 x End stops for each axis (6 in total)
3>Coolant enable
4>Uses removable A4988 or DRV8825 compatible stepper drivers
5>Compact design
6>Stepper Motors can be connected with 4 pin molex connectors or soldered in place
7>Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)

DRV8825 Stepper Motor Driver:
1)*Suitable for driving below 8.2V ~ 45V 2.5A stepper motor
2)*Six different stepping resolutions: full, half, 1 / 4,1 / 8,1 / 16,1 / 32.
3)*A simple steps and direction control interface.
4)*Adjustable potentiometer can adjust the maximum output current, resulting in higher step rate.
5)*Automatic current decay mode detection / selection.
6)*Thermal shutdown circuit, undervoltage lockout, crossover current protection.
7)*Ground short-circuit protection and load short-circuit protection.
8)*DRV8825:20*15*11mm/approx 0.79*0.59*0.43inch(L-W-H) .
9)*Heat Sink: 9*9*5mm/approx 0.35*0.35*0.2inch(L-W-H).

DEVELOPMENT BOARD ATMEGA328P CH340:

1. Solved the problem of the traditional DEV board which is compatible with win7 and win8 system.
2. Increase the pin socket, to facilitate the use of DuPont line.
3. Replaced 16u2, so the cost is reduced, to get the maximum benefit consumers
