Connectors & Expansion ports
By default, OpenModem comes with a 4-pole 3.5mm TRRS (mini-jack) connector for connecting to a radio, and a USB Mini-B connector for connecting to a host-device, and a MicroSD card slot for expandability. The MicroSD card is not included.
For illustrative purposes, the photos above show the modem with the two external auxiliary ports populated with an SMA and an aux connector. These connectors are not included by default, and if necessary must be populated according to the users needs.
The expansion ports on the board are likewise unpopulated, and can be populated by the user with any connector type, or have wires soldered directly to them. The photos above show the expansion ports populated with female swiss-pin connectors.
