Does anyone know if this is compatible for DVI + SD compatibility for the RP2350 picomite?

I know there is an order discussion going on in another thread, but I'm based in the UK, and this is much more affordable for an order size of 1.

Just took a quick look at the schedule.
Possibly remove some SMD resistors at the HDMI location, but I haven't seen Peter's diagram yet. The main 8 pins with resistors are correct. (Remove R2, R3, R6,R25, FUSE1)
You can set the rest freely, I thought, otherwise a small modification where the pins cannot be changed.
Furthermore, a nice complete board with HDMI and SD and audio buffer plus filter and charger for Lipo.

No need to remove FUSE1. SJ1 must be bridged in order to connect it, which is open by default.

Sorry Chris.

I have compared the Pico DVI Sock and Olimex HDMI with each other and unfortunately they are different for GP12 to GP19.
Now wait and see which are the pins in the firmware? Haven't seen Peter's schedule yet.

I agree... Not compatible. Compared to matherp's adapter, it uses the right GP pins but connects them to the wrong HDMI pins.
