Comet A65 Board Revision Document

This page documents the revision history for the Comet A65 product line, including the SOM (System-on-Module) and Carrier Board.

SOM (System-on-Module)

The Comet A65 SOM integrates the Intel Agilex 5 FPGA, DDR memory, and primary power management circuitry.

Item	Rev B	Rev C
FPGA Device	A5ED065BB32AE4SR0 (Engineering Sample)	A5ED065BB32AE4S (Production)

Changes:

[Modified] FPGA Device – Updated from Engineering Sample (ES) device A5ED065BB32AE4SR0 to Production-qualified device A5ED065BB32AE4S. The suffix R0 (ES designation) has been removed, indicating fully production-released silicon.

Initial release with Engineering Sample FPGA A5ED065BB32AE4SR0.
Established baseline DDR memory layout, power management, and high-speed connector pinout.

The Comet A65 Carrier Board provides peripheral interfaces, power delivery, and I/O expansion for the Comet A65 SOM.

Item	Rev B	Rev C
Power Input Connector	DC Barrel Jack	2×3 Pin Header
Photo	Rev B – DC Barrel Jack	Rev C – 2×3 Pin Header

Changes:

[Modified] Power Input Connector – Changed from DC barrel jack to a 2×3 pin header. This improves reliability in embedded and industrial deployment scenarios and better aligns with system integration requirements.
