The Micro Solar Flare Apparatus (MiSolFA) is a compact X-ray detector designed to be flown in a near-Earth orbit during the next solar maximum. Together, MisolFA and Solar Orbiter's STIX will be able to obtain for the first time a 3-dimensional view of X-ray emitting regions with two cross-calibrated instruments. If flare footpoints are occulted to one of the pair, they will be able to precisely compare the energy spectra of the coronal and chromospheric sources. Different viewpoints will also enable a quantitative estimation of the energy-dependent X-ray emission ratio as a function of the viewing angle, which can lead to valuable information about the anisotropy of flare-accelerated electron distribution. MiSolFA will be the most compact X-ray imaging spectrometer in space. Thanks to absorbing grids produced using a novel approach and to new CdTe photon detectors with small pixel size and excellent energy resolution, MiSolFA will perform indirect imaging between 10 and 100 keV with 10 arcsec angular resolution, sufficient to separate most hard X-ray footpoint sources from each other. The instrument is small enough to equip a 6-units cubesat such as the GSFC-developed Dellingr platform.
