#15 Changed PCB layout of power supplies.

Type: PCB Change

Reason: DCDCs with new footprints needs to be used.

Impact: None.

#16 Added option to install Heatsink SuperGrip (c).

Type: PCB Change

Reason: Improve optional cooling solution.

Impact: None.

#17 Added capacitors C7 and C8 (100uF, 1V).

Type: PCB Change

Reason: Improve decoupling for "1V" voltage rail.

Impact: None.

#18  Changed PCB layout of Samtec B2B signals.

Type: PCB Change

Reason: Result of this PCN changes.

Impact: The length of the tracks has been changed. Pinot of Samtec B2B connectors is not affected. Changed trace length has to be taken into account in existing designs. Please, check if change in trace length still matches your requirements. Adaption of carrier may be necessary.

Method of Identification

The model code and revision number of the module (e.g. TE0720-03 or TE0720-04) are printed on the top side of the PCB for revision 04 and is missing for revision 03.

Production Shipment Schedule

The new revision 04 will be shipped from October 2022. If the new revision is not suitable for your application and still the former revision of the board is needed, please contact us.
