Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

TX2+ = D2+
TX2- = D2-
1+ = D1+
1- = D1-
0+ = D0+
0- = D0-
TXC+ = CK+
TC- = CK-

You should also connect "5" to 5V.
You'll also need GND, of course.

If I use this from the manual config suggestion and works vga usb
OPTION SERIAL CONSOLE COM2,GP8,GP9
OPTION SDCARD GP13, GP10, GP11, GP12
OPTION AUDIO GP0,GP1', ON PWM CHANNEL 0

Gp14=pin19
Gp15=pin20
Gp16=pin21
Gp17=pin22
Gp18=pin24
Gp19=pin25
Gp20=pin26
Gp21=pin27


would OPTION HDMI PINS 19, 21, 26, 24  work or I got it wrong?
