This I²C extender board from SJTbits greatly expands the operational distance of an I²C (TWI) bus by transparently bridging the connection between individual I²C devices with differential signaling. The board takes the two I²C signals,...

This module is a compact breakout board for ST’s high-power VNH2SP30 or VNH3SP30 motor driver IC, each of which is a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor. The basic...

Description The powerful jrk 12v12 motor controller is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage, and hobby radio control (RC). The controller can be...

Motor connections These wheels fit 2 mm diameter output shafts such as the ones on our sub-micro plastic planetary gearmotors. The tire is not removable. Due to small variances in the sub-micro plastic gearmotor’s output shaft, in some...

The Pololu MinIMU-9 v3 is a compact (0.8″ × 0.5″) board that combines ST’s L3GD20H 3-axis gyroscope and LSM303D 3-axis accelerometer and 3-axis magnetometer to form an inertial measurement unit (IMU); we therefore recommend careful...

Pololu DRV8835 dual motor driver board for Raspberry Pi B+, top view with dimensions. Overview This motor driver kit and its corresponding Python library make it easy to control a pair of bidirectional, brushed DC motors with a Raspberry...

Overview The Pololu dual high-power motor drivers are compact carriers for the VNH3SP30 and VNH2SP30motor driver integrated circuits from ST. The board incorporates most of the components of the typical application diagram on page 8 of...

Overview This powerful brushed DC gearmotor is available in six different gear ratios and features an integrated quadrature encoder with 64 counts per revolution (CPR) of the motor shaft. The motor and encoder portion is available by...

Overview The Pololu A-Star 32U4 Mini boards are general-purpose programmable modules based on Atmel’s ATmega32U4 AVR microcontroller, which has 32 KB of flash program memory, 2.5 KB of RAM, and built-in USB functionality. The A-Star...

This board is a compact (0.4″ × 0.9″) carrier for ST’s LPS331AP MEMS absolute pressure sensor, or barometer; we therefore recommend careful reading of the LPS331AP datasheet (453k pdf) before using this product. The LPS331 is a great IC,...

The Pololu P-Star 25K50 Micro is a general-purpose programmable module based on Microchip’s PIC18F25K50 microcontroller, which has 32 KB of flash program memory, 2 KB of RAM, and built-in USB functionality. Onboard features of the P-Star...

This motor driver shield and its corresponding Arduino library make it easy to control a pair of bidirectional, brushed DC motors with an Arduino or Arduino clone. The board features Allegro’s A4990 dual H-bridge motor driver IC, which...
