Shield R3 Board A4988 Motor Drivers For Arduino

Shield Board +Arduino R3 Board + 4 x A4988 Motor Driver

(1) Shield Board
Version:3.0
:Red
Size(L*W*H):68 x 53 x 18 mm
Voltage: 12~36 V (At the moment the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)

Features:
1.Uses removable A4988 or DRV8825 compatible drivers.
2.The extension board can be used for carving machine, 3 d printer driver expansion board
3.GRBL 0.8 compatible. (Open source that runs on an Arduino UNO that turns G- commands into signals)
4.PWM Spindle and direction pins,4-Axis (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom using pins D12 and D13)
5.Compact design. Motors can be connected with 4 pin molex connectors or soldered in place.
6.Please note that this is an unassembled kit and Basic skills are needed.

(2)A4988 Motor Driver
:Red
Size(L*W*H):20 x 15 x 10 mm
Thermal shutdown circuitry:Yes
Crossover-current protection:Yes
Ground fault protection:Yes
Load short-circuit protection:Yes
Compatible logic supply: 3.3V and 5 V
Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16

Features:
1.Mix with slow current decay modes.
2.Internal UVLO and Low RDS (On) Output.
3.Automatic current decay mode /selection.
4.Synchronous rectification for low dissipation.
