Board design to connect an Arduino Pro Mini to an Ethernet socket, with sensor ports and passive PoE.
This board is designed to be an IOT sensor node, with connections for:
- DS18b20 Temperature sensor
- Door sensor switches
- Breakout header for other boards/sensors
- Rearrange device numbers
- Move SCL/SDA pins
- Rewire Ethernet pins - TP-Out too close to socket
- Greater distance between Eth port and VRM
- Change C15 for a Radial capacitor
