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.

Description。The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large， exposed pads function as probes for the sensor， together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.。To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).。Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!。Get Started with the Soil Moisture Sensor Guide

。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state， the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger， you simply connect a hobby servo and a switch， then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger， we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious， and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller， running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers："A" sets the position the servo sits in while the switch is open， "B" sets the position the servo moves to when the switch is closed， and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor， the CR Servo Trigger board draws very little current， roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor， the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally， the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note：This idea originally came from our friend in the Oakland area， CTP. If you see him， please give him a high-five for us.。SparkFun CR Servo Trigger Hookup Guide。Features。Recommended Voltage：5VDC。Max Voltage：5.5VDC。Current Draw：5mA。Control Continuous Rotation Servos。Three Control Settings。A - sets the position the servo sits in while the switch is open。B - sets the position the servo moves to when the switch is closed。C - sets the time it takes to get from A to B and back。Easy Control with Potentiometers。Configurable Input Polarity。Configurable Response Mode。Compatible with Analog Servos。ISP Header Pins Available for Reprogram

We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.。The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point.
