This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+ and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its integrated DRV8835 dual motor driver operates from 2 V to 11 V, making it a great control option for low-voltage motors. The board can deliver a continuous 1.2 A (1.5 A peak) per motor, or a continuous 2.4 A (3 A peak) to a single motor when configured with both channels connected in parallel.

This small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino-compatible board. Its integrated A4990 dual motor driver operates from 6 V to 32 V and can deliver a continuous 0.65 A to each motor channel, making it a great control option for low-current motors that run on high voltages. The A4990 is configured to limit the peak motor current to about 0.9 A per channel and is protected against reverse-voltage, under-voltage, over-voltage, short-circuit, and over-temperature conditions.

This half-sized perma-proto board from Adafruit functions similarly to a standard perf-board in that through-hole parts must be soldered to the board, but the holes are internally connected like on a 420-point breadboard, with four bus lines that each span the length of the board and 30 rows of electrically connected pins. Unlike breadboards and perf-boards, this flex perma-proto board is made from thin polyamide film, which makes it incredibly flexible. Three mounting holes and its flexible design make this board great for fitting your circuit onto a curved surface or into your wearable electronics project.

This Arduino shield from Adafruit features TI’s CC3000 Wi-Fi module with an onboard ceramic antenna, a microSD card socket, and a designated prototyping area. The CC3000 uses SPI for communication instead of UART, so the communication speed is not limited to a fixed baud rate. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP, and AES, and a built-in TCP/IP stack with a BSD socket interface supports TCP and UDP in client and server mode with up to 4 concurrent socket connections. An Arduino library and example sketches make it easy to get started.
