Good day,
Our latest project requires ethernet, and we would like to add the J1B1211CCD directly to the board, but it appears DigiKey and Mouser are out of stock. However, there are nearly 10,000 RB1-125BAG1A units in stock. I'd like to go with the J1B1, but fear availability may be a problem for a while.
Below is how I am wiring the RB1-125BAG1A. However, I can't find an equivalent to Pin 8, which is grounded on the J1B1211CCD (see PJRC Diagram below). On the spec sheet, the internal resistors appear to be grounded to the shield, but I can't figure out which pin exposes that ground and if it needs to be attached to the Ground on the Teensy.
Also, in general, is this the right way to wire the RB1-125BAG1A, with all the other pins straight to the Teensy 4.1 Ethernet pins? Is
Thanks,
Robert
