Can this display run on 3v3? And can I get it without the socket strips?

Hi Rob,

While the display seems to need 5V power, the logic level will be 3.3V to work with the Pico.

Are you looking to use it with a Pico?

No I want it as a debugging device on my own 3v3 design. I have a bit-banging SPI output that works at high speed to display a value with little intrusion on the running code.

I think it’s just two 74HC595 shift regs that should work fine at 3v3, so all I can see being a problem is the current-limiting resistor values if indeed they are set assuming a 5v VCC.

I can just make my own PCB but at $6.50 I suppose it’s worth a try.
