LED Light Bars & Light Strips The WS2812 (often referred to as a "NeoPixel") has become the standard for addressable LED projects and development board indicator lights. While it may look like a common 5050-sized (5mm x 5mm) SMD LED it's far more advanced. Housed inside the tiny

Photodiodes The BPW34 is a tiny general purpose PiN photodiode. This photodiode has a ton of uses one of which is to use it is a mini solar cell to power your project. The cell is sensitive to a wide range of light wavelengths (430-1100nm) so it should produc

Multi-Color LEDs Ever hear of a thing called RGB? Red Green Blue? How about an RGB LED? These 5mm units have four pins - one for each color and a common cathode (the longest pin). Use this LED for three status indicators or pulse width modulate all three and get mi

Optical Sensor Development Tools A simple breakout PCB for the GP1A57HR photo interrupter (also known as a photogate photodiode or phototransistor). This PCB has three connections for PWR GND and Signal.When the gate is clear SIG will be high (>4.9V). When the gate is blocked b

Cameras & Camera Modules A first for the Raspberry Pi ecosystem: A 64MP camera module that matches the specs of smartphone cameras. The Arducam 64MP Camera Module puts a 64MP sensor with autofocus in the standard Raspberry Pi camera module form factor. Much like the other ca

Optical Sensor Development Tools The SparkFun Qwiic Tristimulus Color Sensor is built around the OPT4048 High-Speed High-Precision Tristimulus XYZ Color Sensor from Texas Instruments. This Sensor features a single-chip high-resolution color sensor capable of measuring four channels

LED Lighting Development Tools This is the FemtoBuck a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog s

LED Lighting Development Tools The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default each channel is driven at 330mA; that current can be reduced by either presenting a

LED Displays & Accessories We are quite familiar with seven-segment displays. We see them on our alarm clocks ovens and microwaves. By adding more segments to each digit you can display more than just numbers! These 14-segment displays allow you to show off all sorts of numb

Optical Sensor Development Tools This version of the QRE1113 breakout board features a digital output using a capacitor discharge circuit to measure the amount of reflection. This tiny board is perfect for line sensing when only digital I/O is available and can be used in both 3.3

Cameras & Camera Modules Based on the 16MP Sony IMX519 sensor the Arducam Camera Module V3 with Autofocus provides Raspberry Pi users with all the power needed to build future-proof projects. Boasting twice the resolution of the V2 (16MP with the V3) its standout feature i
