Products from Pololu Electronics

The Solarbotics SW wheel is compatible with standard Futaba servo hubs such as those on theSpringRC SM-S4303R and Power HD AR-3606HB continuous rotation servos. The plastic wheel is molded from ABS and has a molded-on thermoplastic...

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be...

The Pololu step-up/step-down voltage regulator S8V3A is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) with a single-ended primary-inductor converter (SEPIC) topology. It takes an input...

The Pololu Wixel is a general-purpose programmable module featuring a 2.4 GHz radio and USB. You can write your own software or load precompiled, open-source apps onto the TI CC2511F32 microcontroller at the heart of the Wixel, turning...

The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4" to 32" and an analog voltage indicating the distance, this sensor is very easy...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS709LLFTR-35BB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS709 datasheet...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS714LLCTR-30A-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS714 datasheet (678k pdf) before using this...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS715LLCTR-30A-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS715 datasheet (593k pdf) before using this...

Enclosed battery holder for four AA cells. This holder features a lid that slides over the batteries and snaps into place to fully enclose them. It also features a switch that lets you open and close the electrical connection between the...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS711KLCTR-25AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet...
