Description。The SparkFun Qwiic Dual Solid State Relay is a power delivery board that allows users to switch two AC loads from a low power microcontroller using the SparkFun Qwiic connect system. The board features two 25A/250VAC solid state relays that utilize the Zero Cross Trigger method so you can toggle two loads on a 60Hz AC carrier signal on and off up to 120 times per second!。An ATTiny84 acts as the "brain" of the SparkFun Qwiic Dual Solid Relay to accept I2C commands to toggle the two relays as well as a few other special commands. The I2C address of the ATtiny84A is software configurable so， if you have a seriously big power project in mind， you could daisy chain over 100 Qwiic Dual Solid State Relays.。Messing with such high voltage is dangerous! We've included many safety precautions onto the PCB including ground isolation between the relay and other circuitry and a milled out area isolating each side of AC. However， with all the safety precautions included with the SparkFun Qwiic Dual Solid State Relay， this is still a power accessory for users who are experienced around， and knowledgeable about high AC voltage. If you're not comfortable with handling AC voltage in this way， you may want to check out the IoT Power Relay instead.。Note：The relays are rated for a max of 25A with forced air cooling. If you do not have forced air cooling， 10A max through the relays is recommended.。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。The SparkFun Qwiic pHAT V2.0 for Raspberry Pi provides you with the quickest and easiest way to enter into SparkFun's Qwiic ecosystem while still using that Raspberry Pi that you've come to know and love. The Qwiic pHAT connects the I2C bus(GND， 3.3V， SDA， and SCL)on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses， you can stack as many sensors as you'd like to create a tower of sensing power!。The Qwiic pHAT V2.0 has four Qwiic connect ports(two on its side and two vertical)， all on the same I2C bus. We've also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button(with the option to shut down the Pi with a script). Also updated， the mounting holes found on the board are now spaced to accommodate the typical Qwiic board dimension of 1.0"×1.0". This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header as well as the NVIDIA Jetson Nano and Google Coral.。Note。When placing a Raspberry Pi and the pHAT in an enclosure(like the Pi Tin)， we noticed that the pHAT was not fully inserted in Pi's header pins. For a secure connection， you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.。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。The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution， SPI-compatible， serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals， connecting them at the two ends， and making a temperature gradient between one end and the other(a 'hot' end and a 'cold' one). Once this is achieved， a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end， digitizes the temperature measured and sends that data out the other end via a SPI interface， thereby interpreting the data and translating it for you to read!。With the SparkFun Thermocouple Breakout， the thermocouple's hot junction can be read from -200℃ to +700℃ with an accuracy of ±2℃ while the cold junction， inside the MAX31855K， can only range from -20℃ to +85℃ while maintaining ±2℃ accuracy. The MAX31855K constantly measures the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from +3.0V to +3.6V(+3.0V nominal)and only draws 1.5mA maximum.。The Thermocouple Breakout is designed to accept a standard thermocouple connector， for convenience and compatibility with probes you may already own. These connectors aren't necessary， and you could solder a thermocouple directly into the through-holes labeled '+' and '-'. If you decide to solder the thermocouple directly to the breakout board， it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.。Features。14-bit Resolution。SPI-Compatible， Serial Interface。-200℃ to +700℃ Temperature Reading with ±2℃ Accuracy。3.0V to 3.6V(+3.0V nominal)Required。Accepts Type-K Thermocouple

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.

Description。Passive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 1μA SparkFun EKMB1107112 Qwiic PIR uses an EKM-series PIR sensor from Panasonic(R)paired with an ATTiny84 to interact with it using I2C with the Qwiic system. The EKMB-series PIR sensors are optimized for small movements to offer motion-sensing options for battery powered applications due to the low standby current draw of the sensor(1μA).。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.。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。Buttons are an easy and tactile way to interface with your project， but why would you want to deal with debouncing， polling， and wiring up pull-up resistors? 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!
