Changes
#1 Changed DCDC EN63A0QI (U14) to MP8869SGL-Z and adapted power circuit.
...
Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range signal "PG_SENSE" is triggered.
#5
...
Connect DCDC MP8869SGL-Z (U14) to I2C bus via resistor (R91, R92) (default: fitted) and optionally pull-up resistor (R45, R47) (default: not fitted).
Type: Schematic Change
Reason: Improvement of DCDC handling.
...
Reason: BOM Optimization.
Impact: None.
#22 Changed 100 µF capacitor (C35, C45, C120, C144, C145, C146, C147, C148, C149) from 6.3 V,
...
1206 to 4 V,
...
0805.
Type: Schematic Change
Reason: BOM Optimization.
...
Reason: BOM optimization.
Impact: None.
#27 Removed testpoints from bottom PCB side for signals "GND", "3.3VIN", "RESIN", "JTAGEN", "TMS", "TCK", "TDI", and "TDO".
Type: Schematic Change
Reason: Placement optimization.
Impact: None.
#28 Added testpoint (TP23, TP24, TP25, TP26, TP27, TP28, TP29, TP30, TP31, TP32, TP33, TP34, TP35, TP36, TP39, TP40
