Shields

The ProtoShield makes it easy for you to design custom circuits. You can easily solder TH or SMD ICs on the prototyping area to test them with your Arduino board. The SMD area is designed for a maximum of 24 pins SOIC integrated circuit and the TH area contains a lot of space for the needed components around your project. You can even stick a mini breadboard (not included) on the protoarea for solderless operation. The proto area includes also two power lines (IOREF and GND), two LEDs pads and SPI signals breakout pads for boards with SPI only on the ICSP header like Zero.

• It has a nice standard 0.1×0.1 prototyping grid with big pads
• Comes with Stacking headers and plain header, choose whichever you want when soldering together
• A IC pattern for adding DIP ICs up to 20 pins
• Power rails down the middle and sides
• A reset button and an extra general use button
• 2 3mm general use LEDs, red and green, as well as 2 matching resistors
• A pass-thru ICSP stacking header so you can stack any kind of shield on top, and/or use an AVR programmer
• A surface-mount chip area for up to 14 SOIC size parts
• Compatible with tiny breadboards
• Every pin is brought out!
• Gold plated pads
• 2 x 0.1uF capacitors on either side for extra power stability
• It has a nice standard 0.1×0.1 prototyping grid with big pads

This motor driver expansion board is based on the L293D chip which is designed to drive up to 4 bidirectional DC motors with individual 8-bit speed selection. It can also drive 2 stepper motors (unipolar or bipolar), single coil or double coil, interleaved or micro-stepping. It contains 4 H-bridges which provide up to 0.6 A per bridge (1.2A peak) at voltages from 4.5 V to 36 V. This shield has pull down resistors to keep the motors disabled during power up. It also features a 2-pin terminal block to ensure separate logic and motor external power supplies. This expansion board is compatible with Arduinos Mega, Diecimila, and Duemilanove. This motor driver shield is capable of driving:Four DC motors and two servos, Two DC motors, stepper motor, and two-way servo, Two stepper motors and servos.
