Prototype Board for MEGA2560 R3 Board
MEGA V3 Prototype Shield with small gold square pad spacing, easier for components soldering and SOP28 SMD components,come with a mini breadboard, integrated power indicator,status lights and reset button,very simple and handy.
L293d Motor Driver Shiled/Board
Two connections for 5V Servos, connected to the Arduino's high-resolution dedicated timer – no jitter!
Able to drive 4 DC motors / 2 stepper motors / 2 Servo
Run motors on DC4.5V – DC 25V
Up to 4 bi-directional DC motors with individual 8-bit speed selection(~0.5% resolution)
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping
4 H-Bridges L293D chip provides 0.6A/bridge (1.2A peak) with thermal shutdown protection
Built with internal kickback protection diodes.
Built with pull down resistors keep motors disabled during power-up.
Big terminal block connectors to easily hook up wires (18-26AWG) and power Arduino reset button brought up top.
2-pin terminal block and jumper to connect external power, for separate logic/motor supplies.
