iotSDR, Software Defined Radio Development
A versatile dev board with everything you need to design custom IoT protocols & gateways
iotSDR - Embedding SDR in IoT
iotSDR provides a platform that allows SDR developers and enthusiasts to design innovative algorithms and cutting-edge products. While wide-band SDRs are more versatile, narrow-band transceivers perform better for many IoT-related applications. Accordingly, iotSDR hosts two narrow-band Microchip AT86RF215 transceivers that provide their own base-band cores and have the ability to handle their own I/Q signal streaming. The result is an extremely powerful tool for anyone who is looking to simplify the task of developing, testing, and deploying high-complexity frameworks.
A Powerful FPGA and a GNSS Chip to Round It Out
iotSDR’s Microchip transceivers are backed by a Zynq SoC—which provides an FPGA and a processing system in a single package—as well as a MAX2769 GNSS chip capable of streaming live signal records. That GNSS chip can be used for custom GPS, Galileo, BieDou, and GLONASS receiver development, and is perfect for projects in the location-based services (LBS) domain such as those related to navigation and surveying.
Use Existing Software, Design a Protocol, or Build a Gateway
You can drive the hardware described above using a wide variety of popular open source software, including the Xilinx PYNQ Python framework, Jupyter Notebooks, and GNU Radio.
And if your work is further down the stack, don’t worry. iotSDR still has you covered. If you want to design and implement a physical layer IoT protocol, for example—a protocol like LoRa, SigFox, WightLess, Bluetooth, BLE, 802.15.4, ZigBee, or something of your own design—this board is for you. It’s also a great place to start if you want to build a custom IoT gateway along the lines of The Things Network, LPWAN, or Google’s Thread.
Radio has long been a pillar of modernization and technology, and this remains true in the era of software-defined radio. The Internet of Things, in particular, stands to benefit from the latest advancements in SDR technology. With iotSDR, you can be part of the community that makes that happen.

IEEE 802.15.4 Baseband Cores
iotSDR hosts dual Microchip AT86RF215 transceiver chips, each of which supports separate, hard-coded baseband cores for the sub-1 GHz and 2.4 GHz bands, compliant with IEEE 802.15.4g-2012 and ETSI TS 102 887-1. An output power of 14 dBm and receiver sensitivities down to -123 dBm result in an outstanding link budget of up to 137 dB. The device offers a high flexibility by supporting a variety of data rates with three modulation schemes:
Multi-rate and multi-regional frequency shift keying (MR-FSK)
Orthogonal frequency division multiplexing (MR-OFDM)
Offset quadrature phase-shift keying (MR-O-QPSK).
Simultaneous operation at sub-1 GHz and 2.4 GHz enables new capabilities and provides the right cost structure for smart metering, smart lighting, home energy gateways, and other industrial and automation equipment.
Supported PHYs (IEEE 802.15.4g-2012, IEEE 802.15.4- 2011, and proprietary modes)
MR-FSK: 50 - 400 kbit/s with optional forward error correction and interleaving
