I have a very simple setup which works fine with an Uno.

enter image description here

#include <SevenSegmentTM1637.h>
#include <SevenSegmentExtended.h>
const byte PIN_CLK = 2;
const byte PIN_DIO = 3;
SevenSegmentExtended display(PIN_CLK, PIN_DIO);
void setup() {
 display.begin();
 display.print(F("TEST"));
}
void loop() {}

When I use the very same setup with a Pro Mini (5V 16Mhz), the display doesn't light up. I get monitor outputs and can blink the onboard LED, but no reaction from the TM1637 display.

Does anyone have an idea how to debug or fix this?

I get this output in the console:
