We present an improved mobile and low-cost NMR hardware platform aimed for use in simple NMR relaxometry experiments. The platform includes all necessary hardware, with the exception of the NMR probe itself, in a single enclosure. The platform is versatile, allowing for operation across a wide frequency range and with various NMR probes. The flexible system firmware allows for many relaxometry experiments, including measurement of T1, T2, ρ 0, and self diffusion coefficient (D). The total cost of the system, neglecting the host computer, is less than $750. Documentation on the platform is open source and available online.
