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"

Description。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℃， and an accuracy of ±1.5℃(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!。This version of the board comes equipped with screw terminals to allow for your own Thermocouple's wiring to be hooked up with the turn of a screw. This makes it perfect for a variety of applications， from measuring the temperature of your Crock-Pot to making sure your backyard induction furnace is up to temperature.。In addition， the MCP9600 has four on-board temperature alerts that you can configure! Instead of constantly polling the sensor over I2C， you can set a temperature limit to trigger an interrupt when the temperature reaches a certain value. This frees up your microcontroller and your I2C bus to do more important things. It's also possible to put the MCP9600 into alternate operation modes in order to save power. The sensor supports a burst mode， where it will take a specified number of samples， return the results， and then go to sleep. This low-power mode makes the MCP9600 perfect for portable applications!。We've written an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun MCP9600' or you can get the GitHub repo as a .zip file and install the library from there.。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 Qwiic Thermocouple Amplifier。Features。Temperature Range of -200℃ to 1350℃。Four Onboard Temperature Alerts。Resolution of 0.0625℃。Screw Terminal Connector。ADDR Jumper for variable I2C Addresses(default address of 0x60)。2x Qwiic Connectors

The Qwiic Button with built-in green LED simplifies all of those nasty worries away into an easy to use I2C device! Utilizing our Qwiic Connect System， using the button is as simple as connecting cable and loading up some pre-written code!。If you need multiple buttons for your project， fear not! Each button has configurable I2C address， so you can daisy-chain multiple buttons over Qwiic and still address each one individually. We've got an example in our Arduino library that provides super-easy way to configure your Qwiic Button to whatever I2C address you desire. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button' or you can get the GitHub repo as .zip file and install the library from there.。In addition to handling blinking and debouncing， the Qwiic Button has configurable interrupts that can be configured to activate upon button press or click. We've also taken the liberty of implementing FIFO queue onboard the Qwiic Button where it keeps an internal record of when the button was pressed. This means that code on your microcontroller need not waste valuable processing time checking the status of the button but instead can run small function whenever the button is pressed or clicked!
