    End-Of-Life #11130: End-Of-Life Notification
    Products Affected: CFAF240400C0-030SC-A1-1, CFAF240400C0-030SC-A1-2, CFAF240400E0-030TN-A1-2, CFAF240400E0-030TN-A1-1
    Date Issued: June 9, 2022
    Summary: End-Of-Life Notification
    Description: Some modifications are being made to the PCB design to improve reliability and manufacturability. The board cutout for the capacitive touch screen is being moved and the reset line to the EVE chip is being routed to the reset pin for the helper processor onboard.

    The parts are being replaced as follows:
    CFAF240400C0-030SC-A1-1 -> EOL and replace with CFA240400E1-030TC
    CFAF240400C0-030SC-A1-2 -> EOL and replace with CFA240400E1-030TC-KIT
    CFAF240400E0-030TN-A1-1 -> EOL and replace with CFA240400E1-030TN
    CFAF240400E0-030TN-A1-2 -> EOL and replace with CFA240400E1-030TN-KIT
    Reason: The current PCB design requires the capacitive touch screen FPC tail to be stretched and needs to be given more slack.

    The reset line is not brought out to the helper processor on the current PCB revision so a reset toggle does not truly reset the whole system.

    Current PCB revision: 10097 h0v3

    Part Change Notice #11080: Firmware Change
    Products Affected: CFAF240400C0-030SC-A1-1, CFAF240400C0-030SC-A1-2, CFAF240400E0-030TN-A1-2, CFAF240400E0-030TN-A1-1
    Date Issued: March 15, 2021
    Summary: Firmware Change
    Description: The firmware is being updated to better manage the power down sequence.
    Reason: If the power down was very short, it could cause the microcontroller to go into a weird state resulting in abnormal display operation.
    Availability: Will be available in the next couple of weeks. We will release a notice when the cutover occurs.
