The number of pixels of your camera sensor is usually not an issue. Indeed, the higher the magnification, the lower the number of pixels required to achieve the same resolution.
A rough numerical evaluation for BLIPS Macro is following:
Field of view: 10mm – image 16:9 @ 5.99MPixel (3264×1836)
Every pixel side corresponds to 10mm/3264 ≈ 3microns
