g-SPS 1.02 - 4V [DDRV] INTERFACES

On the top PCB side, left to right (bottom PCB side right to left) TOP interface (uController side):
1. RX - uController 4G/3G/GSM RX side pass trough
2. TX - uController side 4G/3G/GSM TX pass trough
3. RST - uController side 4G/3G/GSM RESET pass trough
4. I/O - uController side 4G/3G/GSM POWER CONTROL pass trough
5. DIS - input - DISABLE regulator, active high
6. Vout - additional regulated +4V output
7. Vmain - alternate POWER IN (+5V +16V)- see schema bellow
8. GND - POWER GROUND
9. RI - uController side 4G/3G/GSM RING INDICATOR pass trough
