BabyWR_Carrier: 3V3 Power OR Ideal diodes
The 3V3 at the output of Power-OR U6, U7 is currently only 2V7.
U6 and U7 (LTC4358CDE#TRPBF Ideal diode) are not as ideal as hoped. LTC4358CDE#TRPBF minimal input voltage is 9V.
U6 and U7 should be replaced with an ideal diode that tolerates an input voltage of 3V3.
