Description。This is not your normal Passive Infrared(PIR)sensor! The SparkFun AK9753 Human Presence Sensor Breakout is a Qwiic-enabled， 4-channel Nondispersive Infrared(NDIR)sensor. Each channel has a different field of view， so not only can the AK9753 detect a human， but it can also tell which direction the person is moving. To make it even easier to use this breakout， 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.。The onboard AK9753 is a digital sensor giving you a 16-bit digital value over I2C. Each of the four sensors outputs the IR current in pico-amps. A PIR reading can vary from roughly -200(no human present)to 1500 when a human is detected standing in front of a given channel， but it varies due to environmental factors and other heat sources in view. We've written a full library to control the sensor and included examples showing how to output the sensor readings you need， making this breakout even easier to handle!。Note：The I2C address of the AK9753 is 0x64 and is jumper selectable to 0x65 or 0x67.

Description。Get with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so 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.。This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.。There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.。Note：。The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

。Description。Many of our Qwiic products draw very little current when in standby， but there are some that draw considerably more. Products like our top-end u-blox GNSS boards in particular. There are times when you wish you could switch them off to save power， and the Qwiic Power Switch(QPS)allows you to do exactly that!。Based on the PCA9536 4-Bit I2C I/O expander， the QPS can completely disconnect any attached devices so you can minimize your current draw and extend your battery life when you need to.。The QPS also includes a PCA9306 level-translator which acts as a bus isolator. Want to mix 400kHz and 100kHz I2C devices on the same bus? The QPS will let you do that too! You can isolate the slower devices while you talk to the fast ones. You can leave the slower devices powered up while you do this， or completely switch them off. It's your choice.。If that wasn't enough， we've broken out the two unused GPIO pins so you can use those as extra inputs or outputs for your project too!。Our Arduino Library includes a comprehensive example showing how you can：switch the power； isolate the I2C bus； and use those extra GPIO pins.。Pair some QPSs with the SparkFun Qwiic Mux and you can now not only talk to multiple devices that share the same I2C address， you can selectively switch them off too!。Need extra Qwiic cables?

Description。This is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.。This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!。The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.。SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.。Get Started with the RFM69HCW Hookup Guide。Features。Transmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm steps。Receive sensitivity：down to -120dBm at 1.2kbps。Modulation types：FSK GFSK MSK GMSK OOK。Bit rates(FSK)：1.2kbps to 300kbps。Voltage range：1.8V to 3.6V。Current consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)。Encryption：AES 128-bit(optional)。Packet buffer(FIFO)：66 bytes。0.8"×1.1"
