about pin 1 of rp4... it might be connected on the other side if i think correct it will be connected to +5v and yes we can clearly see that all the others connect up... i guess i have either missed it on the schematic or they forgot to draw all the resistors inside rp4 i guess i have to go other schematics one more time 2017-02-18 0:26 GMT+01:00 Santo Nucifora <santo.nucifora@gmail.com>: > I don't see pin 1 connected but I'll have to take the board out and check > both.
