The Raspberry Pi is a credit card-sized computer with an ARM processor that can run Linux. This item is the Raspberry Pi Model A+, which has 512 MB of RAM, an HDMI output, audio output, RCA composite video output (through the 3.5 mm jack), one USB port, and 0.1″-spaced pins that provide access to general purpose inputs and outputs (GPIO). The Model A Raspberry Pis are smaller and less expensive than the Model B Raspberry Pis. The Raspberry Pi requires a microSD card with an operating system on it (not included). The Raspberry Pi is very popular, with lots of example projects and information available online.

This smart servo from XYZrobot was designed for their Bolide Y-01 Advanced Humanoid Robot, making it well suited for applications that require a lot of strong and complex actuation, such as humanoid robots, hexapod robots, and robotic arms. Unlike common RC hobby servos, these servos are capable of 360° continuous rotation while still offering position control over an effective range of 330°. They feature a TTL serial interface that is used to configure and control the servo and get feedback about position, speed, and temperature.

Note: This is not an RC servo and does not use the same protocol, so they will not work with standard RC receivers and servo controllers.

This sensor is a carrier/breakout board for ST’s VL53L0X laser-ranging sensor, which measures the range to a target object up to 2 m away. The VL53L0X uses time-of-flight measurements of infrared pulses for ranging, allowing it to give accurate results independent of the target’s color and surface. Distance measurements can be read through a digital I²C interface. The board has a 2.8 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
