The LSM303DLM combines a digital 3-axis accelerometer and 3-axis magnetometer into a single package that is ideal for making a tilt-compensated compass. The six independent readings, whose sensitivities can be set in the ranges of ±2 to ±8 g and ±1.3 to ±8.1 gauss, are available through an I²C interface. The carrier board operates from 2.6 to 5.5 V and has a 0.1″ pin spacing.

Clearance: This board is being replaced by the newer LSM303DLHC carrier (which is pin-compatible) and LSM303D carrier.

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.25″-diameter (0.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimized for use in human touch control applications.

This tiny breakout board for TI’s DRV8835 dual motor driver can deliver 1.2 A per channel continuously (1.5 A peak) to a pair of DC motors, and it supports two possible control interfaces for added flexibility of use: IN/IN and PHASE/ENABLE. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors. The carrier board has the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
