The audio power supply has been removed from the board. Audio power will now only be able to be supplied externally.
Hardware Version Changes: h0v2 to h1v0
Reason:
The audio power supply chip is no longer available and it was determined that it would be better for external power supplies to be used to demonstrate the EVE's audio capabilities.

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

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.

Part Change Notice #11051: The controller chip used on the CFAF240400C0-030SC has been discontinued. The parts will be replaced by a CFAF240400C1-030SC
The controller chip used on the CFAF240400C0-030SC has been discontinued. The parts will be replaced by a CFAF240400C1-030SC
Impact:
Physically, this will be a drop-in replacement. Changes will have to be made to initialization code.
Recommendation:
Sample code for the CFAF240400C1-030SC will be available in the fourth quarter of 2019. Sample CFAF240400C1-030SC parts will be available for purchase at that time
The CFAF240400C0-030SC is not recommended for new designs
Availability:
The CFAF240400C1-030SC will be available when current stocks of the CFAF240400C0-030SC are depleted
