## Debug Ports
See [3DR Pixhawk 1 > Debug Ports](../flight_controller/pixhawk.md#debug-ports)
### Console Port
The [PX4 System Console](../debug/system_console.md) runs on the port labeled [SERIAL4/5](#serial-4-5-port).
::: tip
A convenient way to connect to the console is to use a [Zubax BugFace BF1](https://github.com/Zubax/bugface_bf1), as it comes with connectors that can be used with several different Pixhawk devices.
Simply connect the 6-pos DF13 1:1 cable on the [Zubax BugFace BF1](https://github.com/Zubax/bugface_bf1) to the Pixhawk `SERIAL4/5` port.
![Zubax BugFace BF1](../../assets/flight_controller/mro/dronecode_probe.jpg)
:::
The pinout is standard serial pinout, designed to connect to a [3.3V FTDI](https://www.digikey.com/en/products/detail/TTL-232R-3V3/768-1015-ND/1836393) cable (5V tolerant).
| 3DR Pixhawk 1 | | FTDI | |
| ------------- | --------- | ---- | ---------------- |
| 1 | +5V (red) | | N/C |
| 2 | S4 Tx | | N/C |
| 3 | S4 Rx | | N/C |
| 4 | S5 Tx | 5 | FTDI RX (yellow) |
| 5 | S5 Rx | 4 | FTDI TX (orange) |
| 6 | GND | 1 | FTDI GND (black) |
The wiring for an FTDI cable to a 6-pos DF13 1:1 connector is shown in the figure below.
![Console Connector](../../assets/flight_controller/mro/console_connector.jpg)
The complete wiring is shown below.
![Console Debug](../../assets/flight_controller/mro/console_debug.jpg)
::: info
For information on how to _use_ the console see: [System Console](../debug/system_console.md).
:::
### SWD Port
The [SWD](../debug/swd_debug.md) (JTAG) ports are hidden under the cover (which must be removed for hardware debugging).
There are separate ports for FMU and IO, as highlighted below.
![Pixhawk SWD](../../assets/flight_controller/mro/pixhawk_swd.jpg)
The ports are ARM 10-pin JTAG connectors, which you will probably have to solder.
The pinout for the ports is shown below (the square markers in the corners above indicates pin 1).
![ARM 10-Pin connector pinout](../../assets/flight_controller/mro/arm_10pin_jtag_connector_pinout.jpg)
::: info
All Pixhawk FMUv2 boards have a similar SWD port.
