2. Onboard I/O Connector

This chapter provides information about the SOM-9X20 's onboard I/O connector and its functionality.
2.1 Wi-Fi & Bluetooth Micro-Miniature RF Antenna
Connectors
The SOM-9X20 comes with an onboard Wi-Fi + BT 4.1 combo LGA module that has Wi-Fi and Bluetooth micro-
miniature RF antenna connectors which connect the Wi-Fi and Bluetooth antenna. The micro-miniature RF
antenna connectors are labeled as "ANT1" (Wi-Fi/BT) and "ANT2" (Wi-Fi).

Note:
The RF connector uses a standard 2x2mm size RF receptacle connector which is to be used in conjunction with the
M.2 boards/modules. In addition, the RF receptacle on the module can support either 0.81mm or 1.13mm diameter
cable but it is recommended to use 1.13mm diameter cable for lower loss and 1.2mm max. mated height for low
profile design. An example of a plug connector is the IPEX 20611-001R.

GPS Micro-Miniature RF Antenna Connector

The SOM-9X20 comes with a GPS micro-miniature RF antenna connector which connects the GPS antenna. The
GPS micro-minitiature RF antenna connector is labeled as "J2".

Notes:
1. An example of a plug connector is the HIROSE X.FL-LP(P)-068 with 1.13mm coaxial cable.
2. The output power is 3.3V/ 50mA for GPS active patch antenna.
