Not Subject to NDA
PAD Signal I/O Function Type Comment
P12 Reserved - Reserved

R4 RFU -
Reserved for future use. Not
connected internally
Can be tied to
GND
Table 7: Pin-out
Note: When the UART signals are used as the communication port
between the host and the modem, the RTS must be connected to GND
(on the module side) if flow control is not used.
If the UART port is not used, all UART signals can be left
disconnected.
Note: Unless otherwise specified, RESERVED pins must be left
unconnected (floating).
Note:
The following pins are unique for the LE910Cx and may not be
supported on other (former or future) xE910 family modules. Special care
must be taken when designing the application board if future compatibility
is required.
REF_CLK
SPI_CS
USB_ID
I2C_SCL
I2C_SDA
ADC_IN2
ADC_IN3
Note: The pin out of LE910Cx-WWX’s is perfectly same as LE910Cx
even if the demission is a little bigger than others.
