Qwiic Spectral Sensor
AS7341
-
The AS7341 is an 11-channel spectral sensor from AMS that covers wavelengths between 350nm to 1000nm. It features eight channels that span the visible spectrum and there's a channel for Near IR, clear, and flicker detection up to 2kHz. Point a spectral sensor at an object and it measures the reflected or absorbed electromagnetic wavelengths.

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.

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 Qwiic Thermocouple Amplifier
MCP9600 (Screw Terminals)
-
The MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface, accessed over our Qwiic system. Inside the chip are two temperature sensors, one for the thermocouple itself (the hot junction) and one for the chip itself (the cold junction). As a result, the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625°C, and an accuracy of ±1.5°C (worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!

SparkFun RJ45 MagJack Breakout
-
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 breakout is equipped with the RJ45 MagJack connector already soldered to the board which mean you no longer need to solder the connector to the board yourself or worrying about buying them separately!

SparkFun ESP8266 Thing
Dev Board (with Headers)
-
This is the SparkFun ESP8266 Thing Dev Board --- a development board that has been solely designed around the ESP8266, with an integrated FTDI USB-to-Serial chip. The ESP8266 is a cost-effective and very capable WiFi-enabled microcontroller. Like any microcontroller, it can be programmed to blink LEDs, trigger relays, monitor sensors or automate coffee makers. With an integrated WiFi controller, the ESP8266 is a one-stop shop for almost any internet-connected project. To top it all off, the ESP8266 is incredibly easy to use; firmware can be developed in Arduino and uploaded over a simple serial interface. The ESP8266 Thing Development Board breaks out all of the module’s pins with pre-soldered headers, and the USB-to-serial converter means you don’t need any peripheral components to program the chip. Just plug in a USB cable, download the Arduino board definitions, and start IoT-ing.

SparkFun RGB LED Breakout
WS2812B
-
This is a breakout board for the WS2812B RGB LED. The WS2812B (or "NeoPixel") is actually an RGB LED with a WS2811 built right into the LED! All the necessary pins are broken out to 0.1" spaced headers for easy bread-boarding. Several of these breakouts can even be chained together to form a display or an addressable string.

SparkFun Qwiic Twist
RGB Rotary Encoder Breakout
-
The SparkFun Qwiic Twist is a digital RGB rotary encoder breakout that is also able to connect to our Qwiic Connect System. The Twist takes care of all the various interrupts, switches, PWM'ing of LEDs, and presents all those features over an easy-to-use I2C interface. The Qwiic Twist was designed to get rid of the large mass of wires that are needed to implement an RGB encoder in a breadboard enabling you to stop messing around with interrupt debugging and get back to your project! 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 Analog/Digital MUX Breakout
CD74HC4067
-
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip's address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!

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.

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."
