I recently bought the RJ45 breakout board with magnetics, SKU: BOB-13021. However, the documentation does not specify the pinout for 1000Base-T. What is the breakout board pinout (P1 - P8) in relation to the following ethernet signals?
1000Base-T:
Pin 1: DA+, GREEN/WHITE
Pin 2: DA-, GREEN
Pin 3: DB+, ORANGE/WHITE
Pin 4: DC+, BLUE
Pin 5: DC-, BLUE/WHITE
Pin 6: DB-, ORANGE
Pin 7: DD+, BROWN/WHITE
Pin 8: DD-, BROWN
P1 is Ethernet RJ45 pin 1
P2 is Ethernet RJ45 pin 2 and so on through P8.
Thanks for the reply. Are you certain of that pinout? I found this forum post (https://forum.core-electronics.com.au/t … ut/13330/2) that indicates:
P1 = Transmit+
P2 = Transmit-
P7 = Receive+
P8 = Receive-
When I soldered an ethernet cable to the breakout using P1-P8 straight pinout, it did not connect when tested with a PC. When I soldered according to the above pinout, it was able to connect. However, this is for 10 or 100Base, and I’m looking for 1000Base pinout (which uses all 8 wires).
Thought I was certain, but after looking at the [datasheet for the jack itself, I’m beginning to think it’s 10/100 only. 
Especially when compared to a [datasheet for a 1000base-T jack.

^I agree; the schematic for the jack https://www.sparkfun.com/datasheets/Pro … agJack.pdf makes me think they are only wired for 6 pairs internally
