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 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.

SparkFun 2D Barcode Scanner Breakout
-
The SparkFun 2D Barcode Scanner Breakout is a nifty little breakout board featuring the DE2120 barcode scanner module from DYScan. The DE2120 reads 20 different barcode symbologies (both 1D and 2D) using a camera coupled with on-board image processing to identify and decode everything from UPC codes to QR codes. The module also features two LEDs: one for illumination and one to project the red line that you're used to seeing from laser-based scanners.

SparkFun FTDI Basic Breakout
Beefy 3
-
This is SparkFun Beefy 3 FTDI Basic Breakout for the FTDI FT231X USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout, the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.

CO₂ Sensor
STC31 (Qwiic)
-
Do you need to be able to sense CO2 concentrations of up to 100%? If so, the STC31 is the sensor for you! The Sensirion STC31 thermal conductivity sensor has two CO2 measurement ranges: 0 to 25 vol%; and 0 to 100 vol%. The measurement repeatability is 0.2 vol%, with a stability of 0.025 vol% / °C. The measurement accuracy depends on the measurement range: 0.5 vol% + 3% measured value; 1 vol% + 3% measured value.

SparkFun Pressure Sensor Breakout
MS5803-14BA
-
This is the MS5803-14BA Pressure Sensor Breakout, a high resolution pressure sensor with both an I2C and SPI interface. This MEMS pressure sensor measures the absolute pressure of the fluid around it which includes air, water, and anything else that acts like a viscous fluid. Depending on how you interpret the data, you can determine altitude, water depth, or any other tasks that require an accurate pressure reading. What makes the MS5803-14BA unique is the the gel membrane and antimagnetic stainless steel cap that protects against 30 bar water pressure.

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.
