Nitrogen-vacancy (NV) centers in diamond have emerged as important tools for quantum sensing, with applications ranging from magnetic field to temperature measurements. Achieving high sensitivity in such applications requires precise coherent spin control.However, conventional lab-based setups often rely on bulky, advanced, and costly components, limiting accessibility and scalability. Therefore cost effective and compact sensing platforms are getting more important for research and industry [1]. In this work, we investigate the use of the Red Pitaya platform -a commercial off-the-shelf (COTS), customizable, and cost-effective FPGA platform- as an alternative solution. This versatile hardware enables both signal generation and acquisition necessary for measuring T1 and T2 times in NV centers. The setup demonstrates a promising compact and cost effective alternative to conventional systems, suitable for magnetic and temperature sensing. It paves the way for portable, low-cost solutions in quantum sensing applications and can be adapted for different usecases and measurement environments.
