Pololu DRV8835 Dual Motor Driver Kit for Raspberry Pi B+

via Pololu - New Products

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.

The P-Star 25K50 Micro is a tiny programmable module featuring Microchip’s PIC18F25K50 microcontroller. It packs a Micro-USB interface and 16 digital input/output pins onto a board measuring only 1″ × 0.6″ and ships preloaded with a USB bootloader, so no external programmer is required.

Pololu A4990 Dual Motor Driver Shield for Arduino

via Pololu - New Products

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.

Adafruit Flex Perma-Proto Half-Sized Breadboard Flex-PCB

via Pololu - New Products

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.

Adafruit Perma-Proto Full-Sized Breadboard PCB (3-Pack)

These full-sized perma-proto boards from Adafruit function similarly to standard perf-boards in that through-hole parts must be soldered to the board, but the holes are internally connected like on a 840-point breadboard, with four bus lines that each span the length of the board and 60 rows of electrically connected pins. They also feature a labeled silkscreen and mounting holes, which make it easy to transfer your prototype to a permanent circuit board and project box. These boards are sold in packs of three.

These quarter-sized perma-proto boards from Adafruit function similarly to standard perf-boards in that through-hole parts must be soldered to the board, but the holes are internally connected like on a 210-point breadboard, with four bus lines that each span the length of the board and 15 rows of electrically connected pins. They also feature a labeled silkscreen and mounting holes, which make it easy to transfer your prototype to a permanent circuit board and project box. These boards are sold in packs of three.

Raspberry Pi Model B+

via Pololu - New Products

The Raspberry Pi is a credit card-sized computer with an ARM processor that can run Linux. This item is the Raspberry Pi Model B+, which has 512 MB of RAM, an Ethernet port, HDMI output, audio output, RCA composite video output (through the 3.5 mm jack), four USB ports, and 0.1″-spaced pins that provide access to general purpose inputs and outputs (GPIO). The Raspberry Pi requires a microSD card with an operating system on it (not included). The Raspberry Pi is very popular, with lots of example projects and information available online.

Thin (2mm) USB Cable A to Micro-B, 6 ft, Low/Full-Speed Only

via Pololu - New Products

This Micro-USB cable is extremely thin (2mm diameter), light, and flexible, which makes it easier to use than bulkier cables that tend to take up more desk space and pull small devices off tables. The 6 ft (1.8 m) cable is terminated on one end by a Type-A USB plug and on the other by a Micro-B USB plug. Note that this cable is only capable of low- and full-speed USB, not high-speed USB.

Pololu Stamped Aluminum L-Bracket for NEMA 17 Stepper Motors

via Pololu - New Products

This black anodized aluminum bracket lets you securely mount typical NEMA 17-size stepper motors to your project. The bracket features several slots and holes for a wide variety of mounting solutions, and four M3×6mm screws are included for securing the motor to the bracket.
