SparkFun Qwiic Quad Relay
-
The SparkFun Qwiic Quad Relay is a unique power accessory board that has been designed for switching not one but four high powered devices from your Arduino or another low powered microcontroller using I2C. Taking a look at the board, the Quad Relay has four individual relays rated up to 5 Amps per channel at 250VAC or 30VDC. Each channel also has its own uniquely colored LED, silk for easy identification, and screw terminals for optional connection. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system!

SparkFun RedBot Sensor
Line Follower
-
The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.

SparkFun Triple Axis Accelerometer Breakout
ADXL345
-
This new version adds two standoff holes as well as an extra decoupling capacitor. The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +-16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

SparkFun Triad Spectroscopy Sensor
AS7265x (Qwiic)
-
The SparkFun Triad Spectroscopy Sensor is a powerful optical inspection sensor also known as a spectrophotometer. Three AS7265x spectral sensors are combined alongside a visible, UV, and IR LEDs to illuminate and test various surfaces for light spectroscopy. The Triad is made up of three sensors; the AS72651, the AS72652, and the AS72653 and can detect the light from 410nm (UV) to 940nm (IR). In addition, 18 individual light frequencies can be measured with precision down to 28.6 nW/cm2 and accuracy of +/-12%. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

SparkFun GPS Breakout
XA1110 (Qwiic)
-
The SparkFun XA1110 GPS Breakout is a small I2C-supported module built for easy hookup, thanks to our Qwiic Connect System. Equipped with the XA1110 GPS module from GTOP, this board utilizes the MediaTek MT3333 chipset, loaded with specialized SparkFun firmware that enables both I2C and serial ports simultaneously. Using I2C means you won’t have to tie up your serial port with GPS, leaving it open to other possibilities.

Digital Multimeter
Basic
-
The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. You can use the multimeter to measure DC and AC voltage, DC current, resistance, continuity, and test diodes. With this version we've done away with the bright flashy colors that can get us into trouble and gone with a nice, neutral gray. This multimeter should provoke no strong feelings one way or the other, we know this because our guts say "maybe."

LilyPad Temperature Sensor
-
Detecting temperature changes has never been easier. The MCP9700 is a small thermistor type temperature sensor. This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C. Doing an analog to digital conversion on the signal line will allow you to establish the local ambient temperature. Detect physical touch based on body heat and ambient conditions with this small sensor.

SparkFun IR Thermometer Evaluation Board
MLX90614
-
This is an evaluation board for the MLX90614 IR Thermometer. The sensor is connected to an ATmega328 running at 3.3V with a STK500 (Arduino) 8MHz bootloader. Code can be loaded through the FTDI basic interface and the Arduino environment.

SparkFun LED Driver Breakout
TLC5940 (16 Channel)
-
The TLC5940 is a 16 channel PWM unit with 12-bit duty cycle control (0-4095), 6 bit current limit control (0-63), and a daisy chainable serial interface. This breakout board is a good way to take full advantage of this useful IC. All 16 PWM channels are broken out to standard 0.1" headers, which run alongside convenient voltage and ground rails. Also, because the TLC5940 can be daisy-chained, the breakout is designed to support that feature. On the left-hand side of the board all serial inputs are broken out to 0.1" headers and likewise with output on the right-hand side.

SparkFun USB MicroB Plug Breakout
-
We have no idea what USB device you are hooking up to, but if you want to access the microUSB port on something, you might want this. We broke out all five pins with a vertical microUSB connector for your prototyping needs.

SparkFun Analog MEMS Microphone Breakout
ICS-40180
-
The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the InvenSense ICS-40180 analog microphone. This board features an OpAmp to bring the output of the microphone to a usable level, allowing you to plug directly into an ADC on a microcontroller or something like the SparkFun Spectrum Shield.

SparkFun Pulse Oximeter And Heart Rate Sensor
MAX30101 & MAX32664 (Qwiic)
-
The SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor, utilizing two chips from Maxim Integrated: the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing, the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations, digital filtering, pressure/position compensation, advanced R-wave detection, and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small, measuring at 1in x 0.5in (25.4mm x 12.7mm), which means it will fit nicely on your finger without all the bulk.

LoRa 1W Breakout
915M30S
-
Do you need power? This breakout for the 915M30S module from EBYTE is a 1W (30dBm) LoRa transceiver. LoRa is great for long range (miles), low power (in sleep), and low data rates (~500bps). This breakout board is designed to connect to any platform that has SPI and 6 available GPIO. We include a robust edge mount RP-SMA connector to connect large LoRa (915MHz) antennas. In addition, the on-board U.FL connector can be used if you need to get outside a metal enclosure.
