The Conclusive Engineering Kestrel KSTR-SAMA5D27 is a Single Board Computer featuring a SAMA5D27, ARM® Cortex®-A5 based System on Chip from Microchip. Delivering around 785 DMIPS at 500MHz, this is one of the leanest SoCs capable of running a full Linux or FreeBSD operating system.
Kestrel is designed for long battery operation and energy efficiency. It can be powered directly by a Li-Ion or Li-Poly battery thanks to an integrated battery management system. It's capable of several deep sleep states, and has a realtime clock powered by a separate on-board battery, that can be used to manage the board's power cycles and wake/sleep timers.
Kestrel is capable of running realtime workloads, and offers great connectivity options for external devices with a total of over 60 IO lanes and Fast Ethernet with a dedicated controller. All this on a PCB that's smaller than a credit card.
It also delivers advanced security (Arm TrustZone® , tamper detection, secure data storage, secure boot) and high-performance crypto accelerators (AES, SHA and TRNG). |
