SKU: AF-4701

The Adafruit ST25DV16K is a unique I2C-programmable RFID EEPROM breakout that works with mobile phones as an ISO/IEC 15693 (13.56 MHz) NFC tag, but can be dynamically rewritten over I2C by a microcontroller. This makes it ideal for projects where you need to change tag content on the fly — for ex...

SKU: AF-5647

The Adafruit STEMMA Audio Amp is a compact mono Class D amplifier based on the PAM8302 chip, delivering up to 2.5W into 4 Ω speakers from a 2.0–5.5V DC supply. With over 90% efficiency at half a watt into 8 Ω, it's ideal for portable and battery-powered audio projects. This plug-and-play STEMMA ...

SKU: AF-4409

The Adafruit STEMMA Non-Latching Mini Relay lets you switch lamps, fans, solenoids, and other small appliances (up to 250 VAC/DC) using any 3V or 5V microcontroller — no soldering, flyback diodes, or level shifting required. Just connect via the JST-PH STEMMA connector and toggle the signal pin h...

SKU: AF-5791

The Adafruit STEMMA Piezo Driver Amp uses the PAM8904 switched-capacitor driver to amplify signals for piezo elements at up to 300 kHz. With bridge-tied load (BTL) output and up to 3× voltage multiplication, it can deliver approximately 13 Vpp — much louder than driving a piezo directly from a 3V...

SKU: AF-5913 · MPN: ADA5913

The Adafruit STEMMA Reflective Photo Interrupt Sensor uses a TCRT1000 right-angle optical module to detect reflective surfaces. An onboard IR LED emits light, and when an object reflects it back to the IR phototransistor, the output pin drops from high toward 0V — making it easy to detect the pre...

SKU: AF-4026

The Adafruit STEMMA Soil Sensor uses capacitive measurement to detect soil moisture — a more durable approach than resistive sensors that corrode over time. With a single probe and no exposed metal, it avoids oxidation issues and won't introduce DC currents into your plants. The ATSAMD10 microco...

SKU: AF-3885

The Adafruit STEMMA Speaker combines a Class D audio amplifier with a 1W 8 Ω speaker in one slim, portable package. Connect ground, 3–5V power, and an audio signal via the JST-PH STEMMA connector or the alligator/sew-pads — no AC coupling needed, the board handles that for you. Sound quality is ...

SKU: AF-6353 · MPN: ADA6353

The Adafruit STSPIN220 Stepper Motor Driver Breakout makes controlling bipolar stepper motors simple with a GPIO-only interface — just two pins (DIR and STEP) are all you need. It defaults to 1/16 microstepping and supports up to 1/256 microstepping via mode pin configuration, making it ideal for...
