SKU: SF-BOB-09118

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two pho...

SKU: SF-BOB-29195 · MPN: BOB-29195

This compact breakout board makes it easy to work with a male DE9 connector, commonly referred to as DB9. It brings the connector out to a maker-friendly plated through-hole header, so you can wire it into prototypes, test fixtures or custom serial-style cable assemblies.All nine DE9 pins are rou...

SKU: SF-DEV-13743

The SparkFun Level Shifting microSD Breakout is quite similar to the SparkFun microSD Transflash Breakout, but with the included level shifting hardware, this board allows you to utilize a microSD card at Arduino’s SD library’s top speed on a 5V system. With this small breakout board, that is not...

SKU: SF-BOB-29094 · MPN: BOB-29094

A breakout board for the Panasonic EVQWGD001 roller wheel encoder with press-to-select switch. This tactile input device combines a scrolling wheel with a push button in a compact form factor – similar to the scroll wheels found on automotive steering wheel controls. The breakout provides easy a...

SKU: AF-4682

The Adafruit Micro SD SPI or SDIO Card Breakout Board gives you fast microSD card access using either standard SPI or the higher-speed SDIO protocol. Unlike SPI-only breakouts, this board exposes the full SDIO bus with up to 4 data pins for significantly faster read/write speeds — roughly double ...

SKU: SF-SEN-19096

The SparkFun BME688 Environmental Sensor is a breakout that combines a gas scanning sensor with temperature, humidity, and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME688 can detect a wide variety of volatile organic compounds (...

SKU: SF-DEV-22462

The SparkFun DataLogger IoT is a data logger that comes preprogrammed to automatically log GPS and various pressure, humidity, and distance sensors. All without writing a single line of code! The DataLogger automatically detects, configures, and logs Qwiic sensors. It was specifically designed fo...

SKU: SF-BOB-13021

This is the SparkFun RJ45 MagJack Breakout, a simple board that will provide you with a way to put an ethernet port into your breadboard. The SparkFun RJ45 MagJack Breakout is the same one found in our very own mbed Starter Kit and breaks out each pin from the ethernet jack. This rev of the br...

SKU: AF-3515

The Adafruit HTU21D-F is an accurate I²C digital temperature and humidity sensor breakout board. With typical humidity accuracy of ±2% (optimised for 5–95% RH) and temperature accuracy of ±1°C across -30 to 90°C, it's a reliable and affordable choice for environmental monitoring projects. This b...

SKU: AF-3657

The Adafruit ATSAMD09 Breakout with seesaw is a versatile I2C peripheral board built on the Adafruit seesaw framework. Seesaw is a near-universal converter that lets you add GPIO, ADC, PWM, and more to any I2C-capable microcontroller or single-board computer — all over a simple I2C connection. R...

SKU: AF-6359 · MPN: ADA6359

This breakout lets you add an ideal diode to a higher-current DC power path without the usual forward voltage drop of a standard diode. It is designed for 3~23V DC supplies and up to 5A, using the LM73100's back-to-back FETs to keep current flowing in one direction while wasting far less power as...

SKU: AF-419

Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a m...

SKU: FT-OLSH

Connect the 128x128 pixel OLED module to your Arduino-compatible board for a tiny, handy display with a joystick input and piezo sound output! The module can be plugged in directly on top of the shield, or connected via the supplied cable for remote mounting. The top of the shield features an ...
