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 SparkFun LTE CAT M1/NB-IoT Shield with Hologram SIM Card equips your Arduino or Arduino-compatible microcontroller with access to data networks across the globe without needing to provide your own subscriber identity module. This shield adds wireless, high-bandwidth cellular functionality to your IoT project while maintaining low power consumption and a small footprint. The SparkFun LTE CAT M1/NB-IoT Shield is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.。At the heart of the LTE Cat M1/NB-IoT shield is a u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem. Cat M1(Category M1)and NB-IoT(Narrowband IoT)are both Low Power Wide Area Network(LPWAN)technologies that are designed to provide cellular communication to small IoT devices. They operate on LTE network bands just like most smartphones, and should be supported by most cellular network carriers. The u-blox SARA-R4 module communicates over a UART via a simple AT command set. We've provided a library to help you get started with everything from sending SMS text messages to communicating with servers over a TCP/IP connection. Additionally, both the module and library support an I2C GPS interface via a Qwiic connector, so you can plug in a u-blox GPS module and start remotely tracking your project.。Each SparkFun LTE CAT M1/NB-IoT Shield also includes a ceramic, Molex 1462000001 SMD antenna. The antenna has a gain of 3.8dBi around 1.7GHz to 2.7GHz. However, if you would prefer to use an external antenna, we have provided a U.FL connector that can be utilized by simply slicing through a jumper with a hobby knife.。Please be aware that you will need to supply and solder on your own headers before attaching it to your Arduino based device. Also, if you already have your own SIM, we also offer this shield without a card included.。Note:。Be sure to check the。Hardware Overview。section in the Hookup Guide for compatible GPS modules. The onboard Qwiic connector is only designed to support u-blox-based GPS modules. It does not support any other GPS modules or sensors. We are continuing to add more modules so be sure to check back every so often to find out more!。Get Started with the SparkFun LTE CAT M1/NB-IoT Shield Guide
