2.5. Pin Description
The following table shows the DC characteristics and pin descriptions.
Table 5: I/O Parameters Definition
1. ADC input voltage must not exceed 1.8 V.
2. Keep all RESERVED pins and unused pins unconnected.
3. GND pins should be connected to ground in the design.
4. PCM and I2C interfaces are used for VoLTE
*
only.
5. Only BG951A-GL supports GNSS_BOOT (pin 75), GNSS_NRST (pin 76), GNSS_EN (pin 97),
SFNIND_1PPS (pin 98).
6. For BG950A-GL, pin 27 and pin 28 can only be used as CLI UART interface. When pin 27 and pin
28 are used as CLI_TXD and CLI_RXD, the two pins should be connected to pin 95 and pin 94
respectively inside the module. For BG951A-GL, pin 27 and pin 28 can only be used as GNSS
UART interface.
