The S9V11F3S5C3 switching step-up/step-down regulator efficiently produces a fixed 3.3 V (default) or 5 V (selectable) output whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has fixed 3.3 V low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge.

The Pololu Pushbutton Power Switches are sophisticated power control alternatives to bulky mechanical switches. The main function is pushbutton-based latching power control, where one push turns on power and another push turns it off.

This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 36 Voperating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation.

Module with an integrated proximity and ambient light sensor based on the VCNL4040 system. It can detect obstacles in the range of 0 to 20 cm. It communicates via the I2C bus. Adafruit 4161

The core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader. This version does not include any through-hole components or connectors, allowing for customized assembly or standalone use. Pololu 3118

Module with acceleration and rotational speed sensor based on the MPU-6050 system. Equipped with a STEMMA QT connector, it communicates via the I2C interface. Adafruit 3886
