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.

Description。The SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!。The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.。The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.。The STC31 measures CO2 concentrations based on thermal conductivity and 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% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!。The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.。Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.。Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board.

。Description。Passive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.。PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.。Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90°×90° detection area.。Note：The sensitivity of passive infrared sensors is influenced by environmental conditions， so a performance evaluation test under representative conditions is recommended.。Get Started with the SparkFun PIR Breakout Guide。Features。Operating Voltage：2.3。-。4.0V。170 μA。standby current consumption。Lens diameter - 10.4mm。Lens Height - 10.9mm。5m detection distance。90°×90°(±45°)detection area
