LilyPad Light Sensor
-
The LilyPad Light Sensor is a sewable breakout board with an ALS-PT19 light sensor built in and ready to use right away. Each sensor outputs voltage between 0V and 3.3V depending on the level of ambient light shining on it. As more light is applied on the sensor, more current will flow from the board through the signal tab to the microcontroller you connect the sensor to. If the sensor receives no light, no current will flow through it. In a typical indoor lighting situation, the sensor will output around 1 to 2V. Adding this board into your next e-textile or wearable project will really open up the possibilities by being able to incorporate light level sensing capabilities.

USB 32-Bit Whacker
PIC32MX795 Development Board
-
The new version of the UBW32 now uses the PIC32MX795 IC. Based on the work of Brian Schmalz, the UBW32 is a small development board for the new PIC32MX795 32-bit CPU from Microchip. The UBW32 is breadboard friendly and includes all of the external circuitry needed to get the PIC32 up and running. Power can be provided over USB or from an external source. It has three push buttons (Reset, and two user-defined buttons) and five LEDs (Power, USB, and three user defined LEDs). All of the 78(!) of the PIC32's I/O pins are broken out. The board comes pre-loaded with a USB bootloader and special UBW firmware that accepts simple serial commands to control the various I/O functions.

SparkFun FTDI Basic Breakout, 5V
9716
-
This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

Pro Micro
5V/16MHz
-
Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface.

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 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!

SparkFun I2S Audio Breakout
MAX98357A
-
The SparkFun I2S Audio Breakout board uses the MAX98357A digital to analog converter (DAC), which converts I2S (not be confused with I2C) audio to an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals using the I2S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4Ω load. The board can be configured to output only the left channel audio, right channel, or both.

SparkFun GPS Dead Reckoning Breakout
NEO-M8U (Qwiic)
-
The SparkFun NEO-M8U GPS Breakout is a high quality GPS board with equally impressive configuration options. The NEO-M8U takes advantage of u-blox's Untethered Dead Reckoning (UDR) technology. The module provides continuous navigation without needing to make any electrical connection to a vehicle, thus reducing cost of installation for after-market dead reckoning applications.

SparkFun Thermocouple Breakout
MAX31855K
-
The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a 'hot' end and a 'cold' one). Once this is achieved, a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end, digitizes the temperature measured and sends that data out the other end via a SPI interface, thereby interpreting the data and translating it for you to read!

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.

SparkFun Environmental Sensor Breakout
BME680 (Qwiic)
-
The SparkFun BME680 Environmental Sensor is a breakout that combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME680 can detect a wide variety of volatile organic compounds (or VOC for short) to monitor indoor air quality. Combine that with precise temperature, humidity, and barometric pressure and the BME680 can work as a completely standalone environmental sensor all in a 1in. x 1in. breakout!
