The capacitor is rated with the following formula:
Tip: Make the same plot during system verification to check
timings and voltage levels.
Fast Shut Down by Software
The fast shut down can be triggered by AT command.
Communication Ports
Note: It is recommended to add PCB test points to UART, UART_AUX
and USB of unused modules (for products supporting USB), it may be
useful to reflash, test and debug the application. Test points for UART
or USB are fine, however it is recommend to place the pads for a
suitable connector on the port, for convenient access for network
certification testing and access during early development testing.
The USB connector can be “DNP” as long as it is not needed. This
may be more convenient than just test points alone.
USB 2.0 HS
The ME910G1 includes one integrated universal serial bus (USB 2.0 HS) transceiver.
The following table lists the available signals:
USB differential Data (+)
USB differential Data (-)
