Which Teensy? Are you making a pcb?

Check out visualteensy. https://github.com/luni64/VisualTeensy

I also found this board, might be less effort to use instead of the chips. https://www.waveshare.com/w/upload/0/08/LAN8720-ETH-Board-Schematic.pdf

I was mashing together a few different Sparkfun boards, there was a POE board that had all that extra stuff. It should have all your notes in there. I checked the Arduino to MM pins, they look good. Looking at the eval...

Thanks for the groundwork on this Paul. I started an Eagle schematic, pdf attached. I'm not quite done, need to find an LDO and finish up the voltage regulation section. Maybe bring out some pins to a header and add...

Thanks Paul, I grabbed a handful as well. I'll update here if I catch a break and start on a MicroMod ethernet test board.

The battery taps are for charging, so they keep the cells balanced, as you mentioned. Drawing off the taps in different amounts will unbalance them. Will the charger be ok with this? Not sure this is good...

You need 5 or 4 pins connected MOSI SCK CS D/C Reset (can be optional, depends on library) The SPI hardware will dictate MOSI & SCK. You pick the rest of the pins from your available GPIO and define them in your...

Are the T4.1-Lockable available anywhere? Any way to convert a non-lockable to lockable?

Thanks Paul & vjmuzik, perhaps @shawn can chime in on QNEthernet's effort needed, or someone else with the chops to add it. I can whip up a MicroMod board.

@PaulStoffregen I was looking at this, but getting PHYs these days is 39 weeks away. So I've got time to figure out the MicroMod board, but what else is needed to get this to work? When you say software side, does...

The phy has auto-MDIX, which will auto detect a crossover cable and swap the signals. When you plug it in backwards, it will auto correct, but LED won’t work.

Not sure if the network has a router, but I was having issue with my network and found that a dumber network router seemed to work better, back when I started using NativeEthernet. I have a Unifi network at the office,...

I have interest in this as well, but haven't had the time to spend on it, but slowly gathering up components to build it. From what I understand, you will need a grand master clock, which can be pricey, cheapest I...
