Service Module Rev A ECOs (main board)
- 220uF caps should get smaller (physically, too tall)
- Remember to populate R50 with CERN IPMC value.
- We should add a pull-down to U15 pin 1 for when we have no IPMC (added on board 1)
We should add a pull-up to ETH_SW_RESET_N (Has on-board pull-up, so we are OK)
- Traces under mounting splice plate holes
- U23 has wrong DigiKey? part number
- A pull up/down should be added between U24 pin 4 and U23 pin 7
Front panel board changes for Rev B
- Remove level shifter and wire direct uSD card to connector
- Change FT232RQ to FT232RL (TSSOP package)
- Wire
USB_UART_EN
to FT_3V3
through R2 instead of from nDTR
- Change header P/N for headers for longer pins
