a high supply voltage

The Pololu step-up/step-down voltage regulator S9V11F5 is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) that uses a buck-boost topology

Be aware that to switch between I 2 C and SPI interfaces a little bit of soldering between solder pads will be required

which is kind of cool

This DC Current sensor measures DC current

Gravity: Ultrasonic Scanner Kit(180°) Buttons a high supply voltageAn Ultrasonic sensor with scan capability is a must have feature for most robot applications. This Ultrasonic scanner kit provides a cost effective way to have such feature for your robot application. This kit is able to scan up to 120 degree area with 10 400 cm (3. 94 157. 48") detecting range.
