This programmable module combines with a Raspberry Pi to serve as the control center of a small robot or electronics project. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board...

The S9V11x family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. They...

The S9V11x family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. They...

Overview These buck (step-down) voltage regulators generate lower, user-selectable output voltages from an input voltage range of 4.5 to 24 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC...

The 20D mm line of brushed DC gearmotors are available in three different gear ratios, all of which have the same dimensions except for the length of the gearbox. The gearmotor face plate has two mounting holes threaded for M2.5 screws,...

The Pololu A-Star 32U4 Micro is a general-purpose programmable module 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. Onboard features of the A-Star...

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...

This current sensor is a carrier board or breakout board for Allegro’s ACS714LLCTR-05B-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS714 datasheet (678k pdf) before using this product. The...

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...
