The UM6 r2 ultra-miniature orientation sensor from CH Robotics uses rate gyros, accelerometers, magnetic sensors, and an onboard 32-bit ARM Cortex processor to compute sensor orientation 500 times per second. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates. The UM6 was designed specifically to be easy to use—an external enclosure protects sensitive electronics, and connectors make it easy to interface with the sensor without making solder connections to the sensor itself.
The BlueSMiRF is an easy-to-use Bluetooth serial link that works over a range of logic voltages from 3.3 V to 6 V. It has a transmission distance of up to 18 meters. The board carries the RN-42 Class 2 Bluetooth module from Roving Networks, which is a robust, FCC-approved Bluetooth module. A single 0.1″ header for all the pins makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino-compatible RedBoard to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. The V3.1 version includes a RedBoard and detailed instructions for building 15 educational circuits with the kit components.
This sensor is a carrier/breakout board for the ST L3GD20H three-axis gyroscope, which measures the angular rates of rotation about the roll (X), pitch (Y), and yaw (Z) axes. Angular velocity measurements with a configurable range of ±245°/s, ±500°/s, or ±2000°/s can be read through a digital I²C or SPI interface. The board has a 3.3 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.5 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
The SparkFun Weather Shield is an easy-to-use Arduino shield with sensors for measuring barometric pressure, relative humidity, luminosity, and temperature.
This breakout board for Fairchild’s FPF1320 acts as a power multiplexer, allowing you to select which of two power sources is connected to a load while blocking reverse current into either of the sources. It handles up to 1.5 A of current at 1.5 V to 5.5 V and also breaks out a USB Micro-B connector that can be used to supply one of the input power rails.
The RoboClaw motor controllers from Orion Robotics can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 30 A per channel (60 A peak).
The RoboClaw motor controllers from Orion Robotics can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 15 A per channel (30 A peak).
This NEMA 17-size hybrid bipolar stepping motor has an integrated 28 cm (11″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).
This data logger lets you save data to files on any FAT16- or FAT32-formatted SD card easily from an Arduino, which can then be read by most plotting, spreadsheet, or analysis programs. The onboard real time clock (RTC) timestamps all your data with the current time, so that you know precisely what happened when.
This UL-listed 5 W, “wall wart”-style switching power adapter supplies up to 1 A at a regulated 5.25 VDC to 5 V USB devices. The AC adapter works with input voltages of 100 – 240 VAC and has an indicator LED that lets you know it is powered. It has a Type-A USB receptacle (the same as on a laptop or desktop computer) that accepts standard USB cables.
The Hydra is a triple-output power converter from CH Robotics designed to make it easier to get the power you need for your next project. With its palm-sized aluminum case, the Hydra provides all the flexibility of a bench-top supply and only uses a fraction of the desk space. Each of the three outputs can supply about 12 W maximum at voltages ranging from 2.5 V to 14 V, and they can be controlled from a computer via USB or a microcontroller via serial.
