Description。LIDAR has never looked so good! This is the LIDAR-Lite v3HP， a compact， high-performance optical distance measurement sensor from Garmin(TM). The LIDAR-Lite v3HP is。the。ideal optical ranging solution for drone， robot， or unmanned vehicle applications. Each sensor is housed in a durable， IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.。The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz(where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3(that's 65mA as opposed to 105mA while idle， and 85mA instead of 130mA while acquiring).。Each LIDAR-Lite v3HP has a range of 1m to 40m and features an edge-emitting， 905nm(1.3 watts)， single-stripe laser transmitter， 8m Radian beam divergence， and an optical aperture of 12.5mm.

Description。The SparkFun MP3 Player Shield is an awesome MP3 decoder with the capabilities of storing music files onto a run-of-the-mill microSD card， thus giving you the ability toadd music or sound effects to any project. With this board you can pull MP3 files from an microSD card and play them using only one shield， effectively turning any Arduino into a fully functional stand-alone MP3 player! The MP3 Shield utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.。The VS1053 receives its input bitstream through a serial input bus(SPI). After the stream has been decoded by the IC， the audio is sent out to both a 3.5mm stereo headphone jack， as well as a 2-pin 0.1" pitch header.。This shield comes populated with all components as shown in the images and schematic； but it does not come with headers installed.

Description。The Raspberry Pi Compute Module 3+ Lite contains the guts of a Raspberry Pi 3 Model B+(the BCM2837 processor and 1GB LPDDR2 RAM). This module allows a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition this module has extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards， opening up more options for the designer.。This is all integrated onto a small(67.6mm×31mm)board that fits into a standard DDR2 SODIMM connector. You get the full flexibility of the BCM2837 SoC(which means that many more GPIOs and interfaces are available than with a standard Raspberry Pi)， and designing the Module into a custom system should be relatively straightforward because all the tricky bits have been put onto the Module itself.。The CM3+ Lite product is the same as CM3+ except the eMMC Flash is not fitted， and the SD/eMMC interface pins are available for the user to connect their own SD/eMMC device. Note that the CM3+ is electrically identical and， with the exception of higher CPU z-height， physically identical to the legacy CM3 products.。Note：The CM3+ modules require a software/firmware image dated November 2018 or newer to function correctly.。Features。Broadcom BCM2837B0， Cortex-A53(ARMv8)64-bit SoC @ 1.2GHz。1GB LPDDR2 SDRAM。Operating Supply Voltage：1.8V， 3.3V。Minimum Operating Temperature：-25C。Maximum Operating Temperature：+80C。HDMI， MIPI， USB， and GPIO interfaces on edge connector

Description。The SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about 3/4 inch width or smaller(spray paint or electrical tape)on a light background. Each array features visible LEDs that point upward when the board is attached(properly)so you can see what the robot sees， brightness control right on the board， and an I2C interface for reading and power control. Here at SparkFun， the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.。The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power， or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.。Note：As you know our Sun emits quite a bit of infrared light， making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!。Features。8 sensor eyes(QRE1113， like in our line sensor breakout)。I2C interface。Adjust IR brightness on the fly with a knob。Switch IR on and off with software。Switch visual indicators on and off with software。Invert dark/light sight with software。Based on the SX1509 I/O expander

Description。The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward 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， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.。To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).。Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!。Get Started with the Soil Moisture Sensor Guide

Description。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.。The SparkFun I2S Audio Breakout board is fairly simple， requiring only a few pin connections to get it up and working. By default the board is configured in "mono" operation， meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you'll need to cut the mono jumper. In addition to being able to select the audio channel output， the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board， the gain however is controlled externally using the gain pin. By default， the board is configured for +9dB， but can be easily changed!。Get Started with the SparkFun I2S Audio Breakout Guide。Features。Supply Voltage Range：2.5V - 5.5V.。Output Power：3.2W into 4Ω at 5V.。Output Channel Selection：Left， Right， or Left/2 + Right/2(Default).。Sample Rate：8kHz - 96kHz.。Sample Resolution：16/32 bit.。Quiescent Current：2.4mA.。Filterless Class D Outputs。No MCLK Required。Click and Pop Reduction。Short-Circuit and Thermal Protection.
