I was wondering what the most recent/newest Arduino is with build in Ethernet port. Because I see a lot of them are "too old": for example:
- Tian => retired
- Yun => retired
- Ethernet => retired
I'm searching for a extreme low power device (battery powered), so no Linux. It's for making a clock.
I want want to power an Arduino and 2 Unify PRO access points from (large) 24V batteries. I also want to Arduino itself having a battery backup.
So I was thinking about this setup:
24V batteries-> DC/DC 48V -> Something like this -> a splitter (hope to find a better one without conversion cable) -> a battery charger -> some ethernet Arduino
The ethernet is for communicating with my domotica and NTP. I have seen that there is a PoE Arduino, but then I'm missing the battery backup and the USB charge port (not really required).
Extra's I will connect to it: - Rotary button - Color OLED - Buzzer (normally we should wake up with dimming light and sound using the OpenHab domotica communication, but a battery and the buzzer are a backups)
