This 900 MHz radio version can be used for either 868 MHz or 915 MHz transmission/reception – the exact radio frequency is determined when you load the software since it can be tuned around dynamically. At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3 V logic. This chip has 32 K of flash and 2 K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. To make it easy to use for portable projects, we added a connector for any 3.7 V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge. Features Measures 2.0' x 0.9' x 0.28' (51 x 23 x 8 mm) without headers soldered in Light as a (large?) feather – 5.5 grams ATmega32u4 @ 8 MHz with 3.3 V logic/power 3.3 V regulator with 500 mA peak current output USB native support, comes with USB bootloader and serial port debugging You also get tons of pins – 20 GPIO pins Hardware Serial, hardware I²C, hardware SPI support 7x PWM pins 10x analog inputs Built in 100 mA lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking Power/enable pin 4 mounting holes Reset button The Feather 32u4 Radio uses the extra space left over to add an RFM69HCW 868/915 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you ned more range than 2.4 GHz (BT, BLE, WiFi, ZigBee) SX1231 based module with SPI interface Packet radio with ready-to-go Arduino libraries Uses the license-free ISM band ('European ISM' @ 868 MHz or 'American ISM' @ 915 MHz) +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software) 50 mA (+13 dBm) to 150 mA (+20 dBm) current draw for transmissions Range of approx. 350 meters, depending on obstructions, frequency, antenna and power output Create multipoint networks with individual node addresses Encrypted packet engine with AES-128 Simple wire antenna or spot for uFL connector Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. Headrs are also included so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Lipoly battery and USB cable not included.

The nRSP-ST is a networked general coverage radio receiver for frequencies from 1 kHz to 2 GHz with up to 10 MHz of spectrum visibility. The nRSP-ST is your own personal remotely accessible SDR which can also be shared with a small number of trusted friends or colleagues. The nRSP-ST addresses the needs of radio enthusiasts who want a 'plug-and-play' solution for remote reception. As well as achieving this, we have addressed typical internet bandwidth limitations with the creation of a novel IQ Lite mode, which efficiently delivers channels of IQ data. We are also introducing the ability to control and store IQ recordings at the remote location. The nRSP-ST is ideal for anyone wanting a wideband remote receiver without needing computer skills and hours of set-up time and ongoing maintenance at the remote location. Features "Plug and play" integrated, networked general coverage receiver: Combines a receiver, a host computer and a whole lot more – all in one box! Apply power and connect to the internet (Ethernet or Wi-Fi) and the nRSP-ST is automatically accessible from anywhere Multi-platform SDRconnectTM software supports local operation or remote access on Windows, MacOS or Linux platforms The nRSP-ST & SDRconnect are configurable for available network bandwidth: In Full IQ mode, the nRSP-ST provides IQ data transfer of the visible spectrum bandwidth (e.g. for high-speed LAN or superfast internet connectivity) In IQ Lite mode, the nRSP-ST provides IQ data of channels up to 192 kHz wide (e.g. for digital decoding by the client) In Compact mode the nRSP-ST provides compressed audio (ideal for slower internet connections) Supports multiple client connections with a simultaneous mixture of connection modes – an admin tool allows you to assign usernames and timeouts to trusted friends or colleagues. All modes support visualization of up to 10 MHz spectrum bandwidth Two remote connection options: Use a remote SDRconnect client or Use the built-in web-server for remote access from any web browsing capable device, including Android/iOS tablets and phones The nRSP-ST offers the ability to record IQ and audio files to a NAS (network attached storage) device if available on the LAN. The 14-bit ADC full featured wideband SDR receiver covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps Remotely monitor up to 10 MHz of spectrum at a time from a choice of 3 antennas Flash upgradable for future feature enhancements Included 1x nRSP-ST Receiver 1x WLAN antenna 1x Power supply 1x Manual Downloads Release notes Software
