SparkFun Proximity Sensor Breakout
20cm, VCNL4040 (Qwiic)
-
The SparkFun Proximity Sensor Breakout is a simple IR presence and ambient light sensor utilizing the VCNL4040. This type of sensor is often seen in automatic towel and soap dispensers or automatic faucets. With the ability to detect objects qualitatively up to 20cm away, you will be able to detect if something is there and if it is closer or further away since the last reading. 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 USB To RS-485 Converter
-
This is the newest revision of this board and this breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps.

SparkFun LED Driver Breakout
LP55231
-
The SparkFun LP55231 LED Driver Breakout is a self-contained solution for developing and deploying the nine-channel I2C LED controller. Remarkably simple, the breakout is equipped primarily with just the LP55231 LED controller IC, plus three RGB LEDs. It also features pads and jumpers for replacing the onboard LEDs with external ones, and configuring the I2C bus, which allows you to daisy-chain up to four LP55231s. This breakout drives the LEDs using Pulse Width Modulation (PWM), so it is well-suited for variable intensity and color-mixing applications!

SparkFun Triple Axis Magnetometer Breakout
MLX90393 (Qwiic)
-
It's time to start utilizing the superior magnetometer, and what better way than to throw it onto an easy-to-use breakout board? The SparkFun MLX90393 Magnetometer Breakout is a triple-axis magnetic sensor board capable of sensing very small fields, while still behaving as one would expect during saturation in larger fields (like a nearby magnet). The MLX90393 breakout can be used as a compass sensor but also works well as a non-contact controller, a flow meter with a magnetic impeller, or a linear actuator position sensor. To make it even easier to to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

SparkFun Spectral Sensor Breakout
AS7263 NIR (Qwiic)
-
The SparkFun AS7263 Near Infrared (NIR) Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7263 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board --- simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic shields, then stack the board on a development board. You’ll be ready to upload a sketch to start taking spectroscopy measurements in no time.

SparkFun Current Sensor Breakout
ACS723 (Low Current)
-
The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!

SparkFun Dev Board
AST-CAN485
-
The SparkFun AST-CAN485 Dev Board is a miniature Arduino in the compact form factor of the Pro Mini. In addition to all the usual features that a mini Arduino has, it possesses an onboard CAN (Control Area Network) and RS485 ports, enabling quick and easy interfacing to a multitude of industrial devices. The CAN485 Dev Board bridges the gap between the maker and industrial spaces!

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 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!

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 Soil Moisture Sensor
-
The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out.
