SKU: AF-5346 | Brand: Adafruit

The Adafruit MCP23017 I2C GPIO Expander Breakout adds 16 extra GPIO pins to any microcontroller or microcomputer over I2C. Each pin can be configured as a digital output (driving up to 25 mA — perfect for LEDs) or as ...

SKU: AF-158 | Brand: Adafruit

Hall effect sensors detect whether a magnet is near. Useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders. I tried dozens of different hall effect sensors to see which one wou...

SKU: AF-189 | Brand: Adafruit

PIR sensors are used to detect motion from pets/humanoids from about 20 feet away (possibly works on zombies, not guaranteed). This one has an adjustable delay before firing (approx 2-4 seconds), adjustable sensiti...

SKU: AF-5221 | Brand: Adafruit

This breakout PCB converts the ANO rotary navigation encoder's non-standard pinout into a straightforward, breadboard-friendly header strip. The ANO encoder combines a rotary encoder with directional and centre-push b...

SKU: AF-5578 | Brand: Adafruit

The BS612 is a compact, fully configurable mini PIR motion sensor that detects movement from approximately 3–8 metres away with a 120° detection spread. Its small form factor makes it ideal for unobtrusive motion-sens...

SKU: AF-157 | Brand: Adafruit

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller.To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to...

SKU: AF-5990 | Brand: Adafruit

The Adafruit Infrared IR Remote Transceiver combines a high-powered IR transmitter and a sensitive 38 kHz IR receiver on a single board. With two 940 nm IR LEDs (one vertical, one horizontal) driven by an onboard N-ch...

SKU: AF-377 | Brand: Adafruit

This high-quality 24-pulse rotary encoder features detented rotation with a satisfying click at each step, a built-in push-button switch, and a panel-mount design. It comes with a soft-touch knob with an arrow indicat...

SKU: AF-1097 | Brand: Adafruit

A simple 4-channel 315 MHz RF receiver module with toggle-type output. No programming, configuration, or microcontroller needed — just power it with ~5V DC and pair it with a matching RF keyfob remote. Each of the fou...

SKU: AF-3845 | Brand: Adafruit

This 3×4 matrix keypad provides 12 buttons (0–9, *, #) in a sturdy, rigid format. It uses a matrix scanning arrangement requiring only 7 pins to read all 12 keys, making it efficient to connect to Arduino, Raspberry P...

SKU: AF-3942 | Brand: Adafruit

The HC-SR04 is an ultrasonic distance sensor that measures distances from approximately 2 cm to 400 cm (best results between 10–250 cm). Widely used in robotics, automation, interactive art, and motion sensing project...

SKU: AF-828 | Brand: Adafruit

An inline flow sensor for measuring liquid or water flow in solar heating, computer cooling, irrigation, and other fluid projects. The sensor uses a pinwheel with a magnet and an external hall effect sensor to count r...

SKU: AF-4979 | Brand: Adafruit

The NeoKey FeatherWing adds two mechanical key switch sockets with individually addressable NeoPixel backlighting to any Feather-format microcontroller. Each socket accepts Cherry MX or compatible switches (Kailh, Gat...
