We present a low cost NMR system aimed for use in simple NMR experiments. The system is based on an Arduino microcontroller platform and a MATLAB interface. Most of the RF chain is broadband, allowing it to be easily used with a wide range of frequencies and transmit/receive coils. The system is capable of several simple NMR experiments, allowing the measurement of T1, T2, ρ 0, and self diffusion coefficient (D). The total cost of the system, neglecting a host computer and bench top power supplies, is less than $400. Documentation on the project is open source.
