Arduino NMR 5.2
Arduino NMR 5.2 is an open source AVR/Arduino PCB design by SoukeyCircuits: a 4-layer, 100 × 75 mm board with 76 components (30 distinct parts). It is built around the SN74LV1T04DBVR, ADG904BRUZ-REEL7, PE4251MLI-Z, TLV74125PDBVR and more. Filed under science & space and audio and test & measurement.
Arduino based NMR spectrometer for use in low field applications.
IMPORTANT DISCLAIMER: The repository here is only the spectrometer for an NMR. You will need to purchase a sufficiently homogeneous magnet and a power amplifier to acquire any kind of measurement. A power amplifier can be purchased from aliexpress for under $100 but your quality and safety will vary significantly. If you are looking for a magnet, there are a few open source options that you can build yourself or commercially available ones.
