USB-C data input and power input

[Smiller]

Hi all,
Is there a reason why my PPM USB-C input cannot read from a Samsung SSD T5 or T3 but can read from the USB -A input?
Also what is the minimum power output to charge PPM whilst displaying video as my Anker portable battery bank doesn’t seem to have enough juice for the job?
Thanks

Hi, welcome!

The PPM has 2 USB-C ports: the rightmost is solely for used for power, the second from right solely for HDMI over USB-C (HDMI-Alt).

For data connections only the USB A port can be used.

As for the power requirements, please check this post and the thread it’s in:

PPM Power requirement

Managed to reach the HW engineer and I have a definitive answer now. PicoPix Max only accepts 15V. Due to thermal and efficiency concerns at this size, some parts inside have a max limit of 15V. 20V parts could not be used. PD optionally allows 15V @ 4A instead of 3A, if local optimisation is of value. Our engineer believes PPM is the perfect candidate for ‘local optimisation’ as 15V4A has better thermal+efficiency characteristics than 20V3A. The supplied power adapter supports this optional…

Hi and thanks for replying. So the USB-C (2ND FROM RIGHT) is for data out to a HDMI? seems wasted given there is a HDMI port. Seems the wrong way around given that the projector is the display. Why would it need to be the source? Or am I missing something.
Thanks

Not HDMI-out but HDMI-Alt(ernate) input. It’s one of the many protocols that USB-C can be a carrier of, and if you have some of the newer laptops without a physical HDMI port but with USB-C that supports HDMI-Alt you can use that to connect it to the PPM.
