CpuBoard Rev 2
Spin Notes

LTM2882 footprint was mirrored.
  LTM2882IY_BGA is the correct footprint.

U39 footprint was QFN_16_3X3 in error.  
  ISL4221E
  Package is 5X5 mm.
  16_QFN_5X5 is the correct footprint.

Remove Q6  Q5  R135  R134
  Un-needed SuperCap circuitry

Add connection: U31 pin 7 to D15 - Anode ( EXT_RESET_N  to Supercap Cntlr )

Swap A3 pins 13 and 14 ( Rx and Tx lines into GNSS-5-CLICK )

Add 22 AWG wire from U31 pin 1 to positive junction of C159 and C160
   Wide trace, actually

Add 1uF 0603 Caps in parallel with C159, C160, C156, C155

Add 100uF, 100nF and 10nF Cap in parallel with C50

Add 100uF Cap in parallel with C200

R26 is now 909k 0603 1%

R28 is now 274k 0603 1%

R21 is now 237k 0603 1%

Add 0.1uF 0603 cap in parallel with R24

Remove D15

Remove R39

Add 10k resistor between pin 1 and pin 2 on Freewave Connector

Cut trace to gate of Q1, bluewire TP90 to CPU GPIO connector J12, pin 13
   Was: Q1 Gate driven from CN1_9
   Now: Q1 Gate driven from CPU signal CN1_21

Add wide trace from pad (F3,D17,C66, TP160) to 3.3V side of C49 to reduce resistance
