For PX4 development and debugging on a Teal One, there is a Nut shell debug port and micro SD slot for logging.
The Nut Shell debug connector is located on the right side of the drone. It is a 6 pin SM06B-SRSS-TB(LF)(SN) connector.
The pinout is:
- Nut Shell UART TX
- Nut Shell UART RX
The micro SD slot for PX4 flight logs is located on the right side near the Nut Shell debug port.
