Keyestudio Photo Interrupter Module

This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. 
By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes 
between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet 
dispensing, general object detection, etc. Gap width = 10mm

9 Axis Gyroscope Accelerometer Magnetic Field Sensor

The MPU-9250 is the world’s smallest 9-axis motion tracking device that incorporates the latest InvenSense design innovations, enabling dramatically reduced chip size and power consumption, while at the same time improving performance and cost.

The MPU-9250 motion tracking device sets a new benchmark for 9-axis performance with power consumption of only 9.3µA and a size that is 44% smaller than the company’s first-generation device. Gyro noise performance is 3x better, and compass full scale range is over 4x better than competitive offerings.

The MPU-9250 is a System in Package (SiP) that combines two chips: the MPU-6500, which contains a 3-axis gyroscope, a 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8963, the market leading 3-axis digital compass.

A4988 Stepper Motor Driver

This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow.

This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control onebipolar stepper motor at up to 2 A output current per coil

XBee 2mW Wire Antenna - Series 2

This is the XBee XB24-Z7WIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.

These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU.
