I am trying to connect an i2c back pack and display to the piano 2.1.
Allo have said this can be done using J19 pins for 5v sda scl and ground... Further I have found a post where they say that 3.3 v is available at the #3 & 4 "NC" pins.
All well and good but the pin identification on the board is different to that in their documentation !!!
See attached screen shots for J19 and note pin 15 & 16 then look at the screen shot of the board and note again pins 15 & 16..???!!!
Anyone tested and can tell me which and where the numbering is for the board..?
