Change Log
----------

- Initial Release (UNVALIDATED DATA)
  Release Date: 11 January 2013

- First validated release
  The detailed changelog has been added in a schematic sheet called "Revision_History".
  Release Date: 22 March 2013

- The NOTE 8 and NOTE 9 have been added in the Audio Codec and JTAG schematic files.
  Release Date: 23 August 2013

- The NOTE 10 has been added in the USB Hub schematic page.
  Release Date: 21 November 2013
  
- New hardware revision, Apalis Evaluation Board V1.1
  Schematic page template has been updated.
  Port Cross Reference has been added to the project.   
  A pull-up resistor R218, 4.7K Ohm has been added to the signal WAKE1_MICO# in the Power Switch schematic page.
  A pull-down resistor R219, 100K Ohm has been added to the signal POWER_ENABLE_MOCI in the Power Switch schematic page.
  New power connector X48 for SATA interface has been added in the Power Supply schematic page.
  New power connector X47 has been added in the Power Supply schematic page.
  HDMI1_HPD signal has been connected to the ESD protection diode D1 in the DVI-I schematic page.
  Level shifter circuit has been implemented to the HDMI1_HPD signal using T18, R4, and R311 in the DVI-I schematic page.
  Resistor R4 value has been changed from 1K to 47K in the DVI-I schematic page.
  Signal VCC_USB01 has been connected to the ESD protection diode D16 in the USB Connectors schematic page.
  Resistors R289 and R290 value have been changed from 22R to 0R in the USB Hub scehmatic page.
  Net PCIE1_PEX_RESET# has been added in the PCIE Express switch schematic page.
  Capacitors C277 and C278 voltage rating have been changed to 16V in the PCIE Connector schematic page.
  A pull-up resistor R312, 1M Ohm has been added to the signal UART1_USB_RXD in the Serial schematic page.
  DAP signal are rearranged between breakout connector X6 and X7 in the Audio codec schematic page.
  Release Date: 09 October 2014

- The NOTE 14 has been added to the schematic page: "NOTE 14: Mini PCIe connector schematic symbol is used in the schematic for the mSATA connector (X36), 
  as Mini PCIe and mSATA use the same physical connector. It is important to note that the mSATA interface specifies the RX+ signal on pin 23 and RX- signal
  on pin 25, whereas the MiniPCIe Card features the RX+ signal on pin 25 and RX- on pin 23. The PCIe interface supports polarity reversal, but not the SATA interface. 
  Since the Mini PCIe connector pin names doesn't match with the mSATA signals, the situation might be confusing. Special attention must be paid while reading or connecting the mSATA signals. "
  Mechanical components part number have been made visible.
  The NOTE 15 has been added to the schematic page: "NOTE 15: Normally, JTAG interface is not required on the Apalis carrier board. For flashing and debugging purpose,
  the system Recovery mode over USB (USB01) and Serial Port (UART1) shall be used. On custom carrier board, customers are recommended to implement the JTAG
  interface only if it is necessary.
  The "NA" notes have been eliminated all over the project since altium can add this note automatically using the assembly variants.
  The bus GPIO name has been modified to GPIO[1..8].
  The notes related to decoupling capacitors position have been corrected.
  The component CON-Molex-67910-5700 has been updated to avoid the PCIe/Sata potential confusion.
  The Value of the resistor R44 has been corrected to match the resistor assembled on the board.
  Release Date: 03 February 2016  

- The NOTE 16 has been added to the schematic page: "NOTE 16: Apalis Evaluation Board V1.1A,  3.3V output power supply is designed for 15W (max). 
  Please check if the available power is enough for the Apalis module of your choice. E.g. Apalis TK1 exceeds this under heavy load."
  Release Date: 20 June 2016 

- NOTE 16 has been updated.
  Release Date: 16 April 2018

- The values of the resistors R44 and R70 has been changed to 5 mOhm and 10 kOhm respectively  
  Release Date: 16 June 2021

- New hardware revision, Apalis Evaluation Board V1.2
  Please check the "Revision History" page to get information about the applied changes.
  Release Date: 10 September 2022
