It is not different. Did you read the Wiki? Revision A5C (Production Version)
Production had some fallout of boards when running the HDMI tests in the previous production run. Resistor values were tweaked to improve the test results. No changes in features or operation of the board. 1) Changed R46,R47,R48 to a 0 ohm. 2) Changed R45 to a 22 Ohm. Revision A5B (Previous 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. Revision A5A (Old Production Version) 1) Boards are built using the XAM3359AZCZ100 processor. 2) PCB Change...LCD noise issue was resolved by adding 47pf bypass caps on some of the LCD signals. 3) PCB Change...Added access to four battery charger signals on the TPS65217 (TS=Temperature Sense, BAT=Battery connection,BATT_SENSE=Battery voltage pin, GND=Ground). Pins are not populated but the four signals are in a 2x2 .1x.1 spacing. 4) PCB Change...Added a power button which allows for wake up, power down, and sleep options. It also provides the ability to alert the processor before powering down to provide an orderly shutdown. It is expected that SW will be used in conjunction with the switch to control the various power modes and transitions from one to the other. By holding the button down for 8 seconds, it will force a power down of the board. 5) Added a 100K pull down resistor from J1 pin 1 to J1 pin 4 to fix the unterminated serial port issue.
