MiniPCIe[edit | edit source]
The MiniPCIe connector supports an add-on providing 4G/LTE modem connectivity.
Description[edit | edit source]
The modem interface is available on the UNICA SBC at the J12 connector.
J12 is a miniPCIe standard connector (TE-1759546-1). This connector is dedicated to an LTE module commonly available on the market.
The 4G/LTE modem then uses the J13 SIM card connector for the network operator connection.
Signals[edit | edit source]
The miniPCIe connector uses the standard interface signals:
- USB host interface for standard 4G/LTE
- Nano SIM card connector for the standard USIM interface
Device mapping[edit | edit source]
The modem peripheral is typically mapped to the corresponding /dev/ttyx device in Linux. The network peripheral is visible under the ifconfig network configuration utility.
Device usage[edit | edit source]
The peripheral uses the standard kernel interface and network protocol stack.
