### Ethernet-2 (#1)

{% hint style="info" %}
Ethernet-2 Output has two JST GH Connectors: a 8 pin and 4 pin. Only one can be used at a time. Use the 4 pin for standard Ethernet, and use the 8 pin full gigabit Ethernet.\
\
Ethernet-2 is connected to the onbaord gigabit Ethernet Switch.
{% endhint %}

#### (4 Pin)

| Pin Number | Signal    |
| ---------- | --------- |
| 1          | ENET 2 B- |
| 2          | ENET 2 B+ |
| 3          | ENET 2 A- |
| 4          | ENET 2 A+ |

#### (8 Pin)

### Silvus USB (#2)

| Pin Number | Signal                                           |
| ---------- | ------------------------------------------------ |
| 1          | 5v + (5v pulled from radio module. 0.5 Amp Max!) |
| 2          | D+                                               |
| 3          | D-                                               |
| 4          | GND                                              |

### UART (#3)

{% hint style="info" %}
This UART port is connected to TELEM 1 (UART 7) of the ARK FPV Flight Controller.
{% endhint %}

{% hint style="warning" %}
UART is always mapped to opposite pairs (RX to TX, TX to RX) requiring inverted wiring. The UART port  on Exodus Dev already has the pairs inverted, so only a 1:1 connection between the compute and mainboard is needed. DO NOT invert any signal pairs between the drone and compute payload.
{% endhint %}

| Pin Number | Signal                           |
| ---------- | -------------------------------- |
| 1          | Unused                           |
| 2          | TX In (Swaps to RX on FC Side)   |
| 3          | RX In (Swaps to TX on FC Side)   |
| 4          | CTS In (Swaps to RTS on FC Side) |
| 5          | RTS In (Swaps to CTS on FC Side) |
| 6          | GND                              |
