Forum Index : Microcontroller and PC projects : Current reference design for HDMI Pico 2 board

Hi,

I am looking for the most current reference design for the HDMI version of the Pico 2 board - is it the one that was advertised in the SC article this Spring (Pico 2 Computer) and is linked on their website? If not, could someone please point me to the thread here?

Another question: I uploaded the files from SC to JLCPCB and one part is not available, the 4.7 mH inductor. They have an inductor with similar specs except that it is 45 Ohm instead of 32 Ohm - would that be acceptable?

Many thanks and best
Thomas

Is this the version that uses a Pico2? The latest version uses an on board RP2350 and has I2S audio so doesn't use those inductors

Its in the .zip ("Pico 2 Computer PCB.zip") on this page:

As it has a 220Ω resistor in series I doubt it will make much difference.
Volhout will let you know if this is wrong.

The SC article is in April 2025, Pico 2 Computer, but so far can't find the TBS thread.
