You could try searching for a technical drawing or blueprint of the LattePanda Sigma. Many manufacturers provide such drawings on their website or have them available upon request. Alternatively, you can search for user manuals or assembly instructions for the device, which may contain detailed drawings of the product. If all else fails, you can try reaching out to the manufacturer directly and ask if they can provide you with the information you need.
