The Baby Orangutan is a complete control solution for small robots, all packed into a tiny 1.2" x 0.7" 24-pin DIP package. Its compact design eliminates bulkier components such as the LCD and switches while retaining the most essential...

This type of buck (step-down) voltage regulator is commonly used in the RC hobby industry, where it is called a “Battery Elimination Circuit” (BEC). It can convert a higher voltage, such as from a motor battery, to a lower 5 V level for...

This board is a compact (0.5″ × 0.9″) breakout board for ST’s L3GD20 three-axis digital-output gyroscope; we therefore recommend careful reading of the L3GD20 datasheet (2MB pdf) before using this product. The L3GD20 is a great IC, but...

Overview These sensors are a great way to quickly detect the presence of nearby objects. It consists of a Sharp GP2Y0D805, GP2Y0D810, or GP2Y0D815 sensor module installed on our tiny carrier board for these sensors, which includes all of...

These premium jumper wires, which are equivalent to our wires with pre-crimped terminalswith 1×1 crimp connector housings already attached, are great for making quick and easy prototyping connections. They are available in three...

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650 g-cm (9 oz-in). The motor has four color-coded wires terminated with bare leads:...

Overview Pololu dual MC33926 motor driver shield for Arduino. This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, brushed DC motors with an Arduino or compatible board, such as the...
