Affected Product | Replacement |
---|---|
TEBT0808-01 | TEBT0808-02 |
Type: Schematic change
Reason: Increase compability to other Trenz Electronic designs.
Impact: Used MIOs are associated with UART0 controller in contrast to the former used UART1.
Type: Schematic change
Reason: Follow up from #1
Impact: Loop back have changed to:
MIO48 connected to MIO49,
MIO68 connected to MIO74,
MIO69 connected to MIO75.
Type: PCB change
Reason: Part is end of life.
Impact: Track it pad no more available.
Type: Schematic change
Reason: Prepare for connection of external signals.
Impact: MGT TX AC coupling capacitors are installed. MGT RX have serial 0Ohm resistors, if AC coupling is needed and not avialable at the external device, resistors could be replaced by capacitors.
Type: Schematic change
Reason: Protect SoM.
Impact: Overvoltage, undervoltage and reverse supply protection are implemented.
Type: Schematic change
Reason: Recommended operation voltage for PS_BATT is max 1.5V.
Impact: PS_BATT is now within recommended operation voltage.
Type: PCB change
Reason: Part 74479787210A is obsolete.
Impact: None.
Type: BOM change
Reason: BOM optimization.
Impact: None.
Type: Schematic change
Reason: Provide alternativ supply connector for easy connection of power.
Impact: Additional power supply connector possible (not assembled).
