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.

using mmcc terminal typed  OPTION HDMI PINS  1, 3, 7, 5 and got a display.
Mick, you now this board, can it be normal, like I built a board cos this was not the dream, a link to get audio and a to d not working same time.

Stan:
HDMI can be stripboard friendly. There are breakout boards. The Adafruit one even has the resistors on it.

I think you'll be able to get the USB HDMI version running on there. GP8/GP9 will probably still work with a USB-TTL converter for the console even though there are pull up resistors on them.

You don't *need* the long female connectors. There are a lot of pins you can't use even if you have them and some (if not all) of the most useful spare ones are already on that little box header and the little 3-pin header.

The 3-pin has GP0 & GP1

CON2 has GP2 & GP3

The 10-gin has GP4, GP5, GP6, GP7, GP8, GP9, GP20, GP21

The HDMI socket has
GP10, GP11, GP12, GP13, GP15, GP15, GP16, GP17, GP18, GP19, GP26

Audio has GP27, GP28

The SD card has GP22, GP4, GP6, GP7 (it shares the SPI with the 10-pin)

There's nothing left to connect anything to. The female connectors are useful for monitoring but most can only be used if you aren't using DVI/ HDMI.
