NMR Control Board
About the NMR Control Board
NMR Control Board is an open source PCB design by ARTS-Laboratory, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 139 × 89 mm, with 54 components from 23 distinct parts.
Other key parts include the NCP715SQ18T2G, LM4565FV-GE2, NCP1117DT50RKG, LM828M5/NOPB and MC7812ABD2TR4G. By type, the board carries 19 test points, 15 capacitors, 7 diodes, 6 ICs, 4 resistors and 1 inductor.
From the project
A compact Time-Domain Nuclear Magnetic Resonance (TD-NMR) system.
Main aspects of this version are: Stable version with all components moved onto one control board that includes duplexer, voltage regulator, and amplifier on one control board. A single large PCB measuring approximately 90 x 140 mm.
