About
The STARBUCK-NANO CubeSat EPS boards are specifically designed to meet the volume and power demands typically required for 3U to 16U CubeSat missions. The STARBUCK-NANO supports 2U and 3U CubeSats with body-mounted solar panels, while the STARBUCK-NANO PLUS features an extended number of Battery Charge Regulators (BCRs) to support high-power CubeSats, from 3U spacecraft with deployable panels up to 12U missions. Each power generation section is self-sufficient and does not require support from any other section within the EPS, and redundant solid-state isolation switches enhance reliability during launch operations. It employs Maximum Power Point Tracking (MPPT) for highly efficient battery charging, maximizing power generation from solar arrays. Analog components and multiple inbuilt protection methods ensure safe operation during transport, launch, and provide a full range of EPS telemetry via the I2C network. The STARBUCK-NANO range comes with 8.2V max power voltage, 3.3V, 5V, and 12V regulated power buses, and Power Distribution Modules with 10 Latching Current Limiters for advanced power management. All power converters required for a CubeSat mission are integrated within a single PC104 card. The system is optimized for Low Earth Orbit (LEO) and is compatible with AAC Clyde Space PHOTON solar panel and OPTIMUS battery ranges, meeting ISS Crewed Flight design requirements when combined. It features a modular design for scalability and easy tailoring to mission requirements, and offers both MPPT or Direct Energy Transfer. The STARBUCK-NANO range has extensive flight heritage since 2014 and is TRL 9.
