Revision 5 fixes all known issues outlined on rev. 2-3. The power supply system is divided in two with a separate 3.3V regulator for both EDBG, and for the Target section. The power supply block diagram for revision 2 and 3 is shown below. The power switch has been redesigned to avoid voltage leakage at power on. The DAC, LIN, and CAN connectors have been moved to ease mounting in production. The RESET level-shifter has been redesigned to avoid leakage when target power is switched off.
