1.
1)
ADC0 and ADC1 cannot be used simultaneously. BG95 supports using of only one ADC interface
at a time: either ADC0 or ADC1. Currently only ADC0 is enabled, and ADC1 will be enabled in the
next hardware design version.
2.
2)
PWRKEY output voltage is 1.5V because of the diode drop in the Qualcomm chipset. PWRKEY
should never be pulled down to GND permanently.
3.
3)
RESET_N will be supported in the next hardware design version.
4. Keep all RESERVED pins and unused pins unconnected.
5. GND pins should be connected to ground in the design.
6. ā*ā means under development.
