1.1 - CATT pinout
Description
The CATT connector combines several different connectors in one.
- Special Addon (SAO)
- JTAG
- PMOD
Because of this multi functional nature, the name for the connector is CATT (Connect all the things), even though there are more kind of things to connect.
SAO
- *DET: Detect, when pulled down during power up, JTAG functionality is provided
- *3V3: Not connected by default, jumper on the PCB needs to be closed to supply 3V3

1.2 - Internal expansion port
Back Expansion layout
Back expansion port
This port is not exposed by default, and modified back covers need to be used to make it accessible. For this reason the port is also named “Internal expansion port”.

Limitations & warnings
- Total for all 3.3v outputs must not exceed 1A of current. It is generally adviced to stay well below this figure.
- VSDCARD power rail can supply at most 100mA total to both the SD card and the expansion header.
- Do not exceed a current of 1A from or to the battery when the battery is connected to the internal battery connector.
