T5 V2.2 2.9" schematics is wrong #6

Hi, the schematics for the above boards seams to be wrong. The red LED is on with digitalWrite(26, LOW); So I assume it has the same connection as all the other boards:

The green one is the power indicator, and the red one can be controlled by GPIO26. The green light can be removed if it is not needed.

Hi @RalfJL I don't know if you still work on this board but I deal with similar schematics issue on the same board when trying to debug with openOCD (issue to find JTAG pinout): it seem that there is "differents" v2.2 revision of this board.... My board have a JP1 20 pin connectors pinout that corresponds to the one here: http://www.lilygo.cn/prod_view.aspx?TypeId=50061&Id=1397&FId=t3:50061:3 But I didn't manage to find schematics, including on this directory (v2.2 don't match). Except for JP1 pinout, my board looks like a v1.2
