Notable changes
B
Initial release of the board
C
1. Resistor matrix RM23 gets replaced by: R133,R134,R135
2. Adjusted the package of H5TQ2G63BFR/MEM4G16D3EABG-125
3. R12 and R15 values changed to 0R
4. NAND_E jumper is changed from PTH to SMD closed
5. 5V_SATA_PWR connector (altogether with 2x2uF) is changed
from WF2S to DW02S and placed near the PWR jack instead of
original position
6. GPIO-4 is now correctly named GPIO-1
7. There is a signal for the power of of the SATA -
PB8/SATA-PWR-EN (r136, c216, r138, t1, t137, fet4)
8. A jumper between 5V_E_SATA and 5V_PWR_SATA is added
9. The micro SD card connector is changed
