4 Module Pins
There are 148 pins on N715-EA and their pads are introduced in 76-pin LCC + 72-pin LGA package. It
supports interfaces including power supply, USB, UART, USIM, PCM, ADC, I2C, and SDIO.
4.1 Pad Lay-out
The following figure shows the pad layout of N715-EA.
There are hardware conflicts between USIM2 interface (pins 145# to 147#) and status indication interface (pins
52# to pin 54#). if you use USIM2 interface, please be sure to leave the status indication interface open; if you
use the status indication interface, leave the USIM2 interface open.
USIM2 is an optional signal, which is configured in the firmware. Therefore, please pay attention to the
difference in firmware version. For more information about how to use the USIM2 interface, please contact
Neoway FAEs.
