Connecting to the serial UART header on the Infinity CPU board
The Infinity CPU Board is used on a number of products including Telos Infinity, Axia IQx, iQs, 25-Seven PDM II, and some Linear Acoustic products.
This board has a serial UART header that is helpful if doing advanced troubleshooting. This port can not be used for configuration, etc. If you are reading this doc hoping to find configuration or other information from this port, move along. There is nothing to see here.
This port is labeled J6 UART and is located along the long edge of the board (opposite the ethernet connectors) next to the MicroSSD slot.

The pinouts are defined as follows (note: pin 1 is closest to the edge of the board):
- Pin 1 - +3V3 (leave unconnected)
- Pin 2 - Transmit (generally White)
- Pin 3 - Receive (generally Green)
- Pin 4 - Ground (generally Black)
