3575-POLOLU Balboa 32U4 Balancing Robot Kit (No Motors or Wheels)
CA$114.22
Build your very own programmable balancing robot with the Balboa 32U4 robot kit! The Balboa control board features an Arduino-compatible ATmega32U4 MCU, motor drivers, quadrature encoders, and a full IMU. This board also has the ability to interface with a Raspberry Pi, making the foundation for a complete Raspberry Pi-controlled balancing robot. Motors and wheels are not included: choose your wheels and motors to personalize your robot. The Balboa 32U4 is a small, user-programmable balancing robot based on the Arduino-compatible ATmega32U4 AVR microcontroller and featuring two H-bridge motor drivers, quadrature encoders for closed-loop motor control, a full inertial measurement unit (3-axis accelerometer, gyro, and magnetometer) for estimating orientation and balancing, and an optional interface for connecting a Raspberry Pi to make a Raspberry Pi-controlled balancing robot.

2836-POLOLU 5V Step-Up/Step-Down Voltage Regulator S9V11F5
CA$32.86
The S9V11F5 switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2 V and 16 V. (Note: it requires an input voltage of at least 3 V to start, but it can operate down to 2 V after startup.) 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 5 V. The very compact (0.3″ × 0.45″) module has a typical efficiency of over 90% and can supply a typical output current of up to 1.5 A when the input voltage is around 5 V.

5V, 2.5A Step-Down Voltage Regulator D24V25F5
CA$57.75
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps.

2730-POLOLU Force-Sensing Linear Potentiometer: 4.0″×0.4″ Strip, Customizable Length
CA$29.15
This force-sensing linear potentiometer (FSLP) from Interlink Electronics is a passive component with internal resistances that independently change in response to the location and magnitude of an applied force. This allows a microcontroller with an analog-to-digital converter (ADC), such as an Arduino or A-Star, to easily determine where and how hard the strip is being pressed, enabling advanced touch-control user interfaces (like menu navigation) or sophisticated tactile sensors. The FSLP is effectively a force-sensing resistor (FSR) that can also simultaneously sense position.
