Multi-channel analysers (MCAs) play a crucial role in spectral measurements, especially in the context of Silicon Photomultipliers (SiPMs) used for gamma spectroscopy. Most commercial MCAs, while highly accurate, remain cost-prohibitive for broader applications. This paper presents the design and implementation of a cost-effective MCA utilizing off-the-shelf components while achieving spectroscopy of gamma particles with reasonable resolution. The MCA board is built around the STM32G4 family microcontroller (MCU), which provides embedded analog components, timers, and high-resolution ADCs. This system is designed to reduce external component requirements, thereby decreasing costs and increasing system reliability. Experimental results demonstrate that the MCA can perform accurate real-time gamma radiation measurements with SiPM detectors. The device offers flexible connectivity options (USB, Ethernet, WiFi). The low-cost, accessible nature of the MCA opens up opportunities for educational and research applications in radiation detection.
