Pin Configuration and Functions
| Position | Signal Name | Signal Description |
|---|---|---|
| 1 | INT | Interrupt signal |
| 2 | +V | System positive rail (*) |
| 3 | +VIN | Step-down input voltage |
| 4 | GND | System ground signal |
| 5 | Rx- | Ethernet signal |
| 6 | Rx+ | Ethernet signal |
| 7 | Tx- | Ethernet signal |
| 8 | Tx+ | Ethernet signal |
*Note: The system positive rail voltage depends on CHESTER power supply option.
Interrupt Pin
The module provides an interrupt output (pin 1), which needs to be connected to the INT pin on the CHESTER mainboard.
