About
GEMINI is NPC Spacemind’s modular Electrical Power System (EPS) for CubeSat platforms from 3U to 16U. It accepts up to 6 independent input channels at 5-20 V each, allowing power from multiple solar panel strings to be combined, and can manage up to 8 parallel battery packs for scalable energy storage (84 Wh per 8-cell pack). Output buses are programmable across 3.3V, 5V, 6/12V and 24V rails to match payload and subsystem requirements, with full over-voltage, over-current and over-power protection and configurable interfaces. The board is compact at 90.2 x 95.9 x 25 mm and 300 g, designed to fit within the standard SM structure stack.
