DescriptionThe Raspberry Pi Zero Case has been designed to fit both the Pi Zero and the Pi Zero W. These official cases consist of several parts and protect the Raspberry Pi Zero from things like rogue wires that might short it out while still allowing full access to the board. Simply snap the RPi into the bottom half of the enclosure， then snap on a desired top. No tools required!Each case has a standard base featuring a cut-out to allow access to the GPIO， and a choice of three lids：a standard lid， a GPIO lid(allowing access to the GPIO pins from above)and a camera lid(which， when used with the short camera cable supplied， allows the Raspberry Pi camera to be fitted neatly inside it). Additionally， each case includes a 4cm long CSI cable and four rubber feet.Note：This case doesNOTinclude a Raspberry Pi or Camera Module.

DescriptionThe SCD30 from Sensirion is a high quality Nondispersive Infrared(NDIR)based CO2 sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in， as well as commands to set the current altitude. For additional accuracy the SCD30 also accepts ambient pressure readings!We've written an Arduino library to make reading the CO2， humidity， and temperature very easy. It can be downloaded through the Arduino Library manager：search for 'SparkFun SCD30' or it can be found in theDocumentstab above.The SCD30 Humidity and Temperature Sensor can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!Note：The SCD30 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete.FeaturesPower supply voltage：3.3V - 5.5VNDIR CO2 sensor technologyIntegrated temperature and humidity sensorBest performance-to-price ratioDual-channel detection for superior stabilitySmall form factor：35 mm×23 mm×7 mmMeasurement range：400 ppm - 10.000 ppmAccuracy：±(30 ppm + 3%)Current consumption：19 mA @ 1 meas. per 2 s.Energy consumption：120 mJ @ 1 measurementFully calibrated and linearizedDigital interface UART or I2C

DescriptionIt's time to say hip hip array for this IR Breakout! The MLX90640 SparkFun IR Array Breakout is equipped with a 32x24 array of thermopile sensors creating， in essence， a low resolution thermal imaging camera. With this breakout you can detect surface temperatures from many feet away with an accuracy of ±1.5℃(best case). To make it even easier to get your infrared image， 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.This specific IR Array Breakout features a55°x35°field of view with a temperature measurement range of -40℃-300℃. The MLX90640 IR Array has pull up resistors attached to the I2C bus； both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno(or equivalent)doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20，000 bytes or more of RAM. To achieve this， we recommend a Teensy 3.1 or above.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the SparkFun IR Array Breakout GuideFeaturesOperating Voltage：3V-3.6VCurrent Consumption：～18mAField of View：55°x35°Measurement Range：-40℃-300℃Resolution：±1.5℃Refresh Rate：0.5Hz-64HzI2C Address：0x332x Qwiic Connection Ports

DescriptionProduct Restrictions：To access certain features of the ATECC608A， users will need to contact Microchip and sign an NDA contract to obtain the complete datasheet. Due to the required NDA - technical support， an Arduino library， and hookup guide are not provided for users on this product.The SparkFun ATECC608A Cryptographic Co-processor Breakout allows you to add strong security to your IoT node， edge device， or embedded system. This includesasymmetricauthentication，symmetricAES-128 encryption/decryption， and much more. As stated above， the ATECC608A has limited Arduino support and the complete datasheet is under NDA with Microchip.This breakout board includes two Qwiic ports for plug and play functionality. 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. The ATECC608A chip is capable of many cryptographic processes， including， but not limited to：Creating and securely storing unique asymmetric key pairs based on Elliptic Curve Cryptography(FIPS186-3).AES-128：Encrypt/Decrypt， Galois Field Multiply for GCMCreating and verifying 64-byte digital signatures(from 32-bytes of message data).Creating a shared secret key on a public channel via Elliptic Curve Diffie-Hellman Algorithm.SHA-256 HMAC Hash including off-chip context save/restoreInternal high quality FIPS random number generator.Embedded in the chip is a 10Kb EEPROM array that can be used for storing keys， certificates， data， consumption logging， and security configurations. Access to the sections of memory can then be restricted and the configuration locked to prevent changes. Each ATECC608A Breakout ships with a guaranteed unique 72-bit serial number and includes several security features to prevent physical attacks on the device itself， or logical attacks on the data transmitted between the device.A summary datasheet for the ATECC608A is available here. The full datasheet is under NDA with Microchip. You will need to contact them for access to the entire datasheet. Meanwhile， the ArduinoATECCX08 Library currently only supports the ATECC608A with SAMD21 Arduino boards.We do have much more support for the ATECC508A version of this chip. Please check out our ATECC508A Hookup Guide and Arduino Library(which includes six examples). This will get you familiar with the basics of elliptic curve cryptography and signing/verifying data with the ATECC508A version of the chip.Note：The I2C address of the ATECC608A is 0x60 and is software-configurable to any address. A multiplexer/Mux is required to communicate to multiple ATECC608A sensors at the default address when on a single bus. If you need to use more than one ATECC608A sensor at the default address， consider using the Qwiic Mux Breakout.Note：The ATECC608A can be only configured once before it isPERMANENTLYlocked. It is advisable that users purchase multiple boards in order to use other configurations and explore the advanced functions of the ATECC608A.Additionally， this boardIScapable of encrypting and decrypting data. However， to access these additional features， you will need to contact Microchip and sign an NDA contract to obtain the complete datasheet.It is recommended that an SparkFun RedBoard Turbo - SAMD21 Development Board is used with this product due to the buffer size required on the I2C bus.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
