Work-In-Progress : Design manufactured and works but a footprint is incorrect.
Alveo U25 Debug Connector to Xilinx JTAG, UART, and I2C.
The Adafruit 4471 footprint I used is off by 0.1". Its headers had to be soldered at an angle to work.
I have successfully used it to debug and program an Alveo U25.
The pinout is not available publicly so the signals had to be traced out.

v0.1-alpha was a basic breakout board for the Alveo U25 Debug Connector. It was never manufactured or tested.
Only two components would have been required: MEC8-113-02-L-D-RA1 and SBH21-NBPN-D07-ST-BK.
