Abstract: Conventional nuclear magnetic resonance (NMR) instruments are large-sized and difficult to carry, which limits their application in fields such as on-site petroleum exploration, food safety, environmental pollution, and quality control. To address this issue, this paper proposes a design of a handheld NMR console. By utilizing an ARM（Advanced RISC Machine）core construction, FPGA（Field Programmable Gate Array）logic design and control program design on a programmable system-on-chip Zynq-7000, the entire handheld NMR console is designed and implemented. After completing the entire design, tests were conducted as several fundamental pulse sequences, including Free Induction Decay (FID), Spin Echo (SE), and Carr-Purcel1-Meiboom-Gill (CPMG), on a self-developed 0.5 T desktop NMR system within our research group. The tests validated the correctness of the overall architecture design and the coordination among various modules. The designed NMR console is 10.6 cm long, 6.0 cm wide, and 1.9 cm high，which significantly reduces its size while also enhancing the real-time performance of the pulse sequence and improving the stability of the console, laying a foundation for further development of portable NMR instruments.
