ADALM-PLUTO

ADALM-PLUTO (PLUTO SDR) is a compact, low-cost USB software-defined radio for education and research. It provides a real RF front end with a wide tunable range (roughly 325 MHz to 3.8 GHz), real-time I/Q sampling at tens of MS/s, and onboard control processing. It’s bus-powered from a laptop and small enough for desk or field use. The hardware and firmware are open, with drivers and firmware available, and it works with GNU Radio, MATLAB/Simulink, and other SDR toolchains. Typical uses include learning SDR concepts, designing/testing digital modulation schemes, performing spectrum analysis, and prototyping wireless links. Getting started: install Pluto drivers, connect to a PC, and run example flowgraphs or Simulink models to transmit and receive.

Equivalent low-cost SDR platforms to ADALM-PLUTO include:
- LimeSDR / LimeSDR Mini (Lime Microsystems)
- HackRF One (Great Scott Gadgets)
- BladeRF (Nuand) 2.x
- SDRplay RSPdx (SDRplay)
- USRP B200/B210 (Ettus Research)
These offer similar USB-connected wideband RX/TX capabilities and software support.

Key features of ADALM-PLUTO (PlutoSDR):
- RF coverage: 325 MHz to 3.8 GHz for TX and RX.
- Instantaneous bandwidth: up to ~20 MHz.
- Real-time sampling: up to about 61.44 MS/s per channel.
- Front-end: direct-conversion I/Q (zero-IF) transceiver.
- Resolution: 12-bit ADCs and DACs.
- Interface: USB 2.0, bus-powered, plug-and-play.

- Pin count: 40 pins (two 20‑pin headers, 2×20).
- Function: Expansion header exposing digital I/O and peripheral interfaces (SPI for transceiver control, I2C, UART, GPIOs) plus clock/power rails for external circuitry and debugging.

The ADALM-PLUTO (PlutoSDR) is manufactured by Analog Devices, Inc. (ADI). ADI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and RF integrated circuits and related development/evaluation products—specializing in data converters, amplifiers, signal-processing ICs, RF transceivers and engineering tools used across communications, instrumentation, industrial, and consumer electronics.

ADALM-PLUTO is a low-cost USB SDR suited for education, research, prototyping and RF sensing in the 325 MHz–3.8 GHz range. Common application areas include:
- Education and labs: RF fundamentals, modulation, DSP, filtering, antennas (with GNU Radio or MATLAB/Simulink).
- Prototyping wireless links: real-time transceiver experiments, baseband processing, channel effects.
- RF front-end evaluation: gain, noise figure, linearity, calibration, impedance matching, filters, amplifiers.
- Spectrum monitoring and RF sensing: wideband spectrum scans, interference characterization.
- IoT/sub-6 GHz experimentation and general RF experimentation.

ADALM-PLUTO is not a single packaged IC. It’s a USB software‑defined radio development board (an assembled PCB with the onboard RF front end).
