Mine are all version A5A. According to CircuitCo's BBB documentation:
Revision A5B (Production Version)
1) Updated the PCB to incorporate the modification that was being done on Rev A5A.There is NO DIFFERENCE AT ALL in functionality between REV A5A and REV A5B.
2) Made the LEDs dimmer for those that could not sleep due to the brightness of the LEDs.
So, in practice there isn't any huge difference. A5A is better for mounting on the heads of sharks though.
