The Locosys LS20031 GPS receiver integrates a MediaTek MT3339 66-channel GPS chip with a ceramic antenna to create a complete GPS module that can track up to 66 GPS satellites at a time. The GPS module supports up to a 10Hz update rate, a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and more than 6 different NMEA ASCII sentences that are output to a TTL-level serial port.

This connector adapts a 5.5 × 2.1 mm DC barrel jack to a pair of screw terminals. The terminals are labeled positive and negative, with the positive terminal connected to the center pin.

This switching regulator uses the SEPIC topology to produce 12 V from input voltages between 2.5 V and 18 V. The wide input range coupled with its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 12 V. The compact (0.4″ × 0.575″) module can supply over 200 mA in typical applications.

This switching regulator uses the SEPIC topology to produce 9 V from input voltages between 2.5 V and 18 V. The wide input range coupled with its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 9 V. The compact (0.4″ × 0.575″) module can supply over 300 mA in typical applications.

This credit-card-sized board crams in a lot of peripherals, making it ideal for prototyping mbed NXP LPC1768 applications. Some features include a 128×32 backlit LCD, 5-way joystick, 3-axis accelerometer, and an RJ45 Ethernet connector.

Great for learning the basics of gears and linkages, this Tamiya kit contains all the parts necessary to make a remote controlled crawler that picks up ping pong balls. The instructions include directions for assembling the kit with either an arm, bucket, or shovel for collecting ping pong balls.
