Every so often, I have to calibrate a number of Si5351 boards, so,one of my VFO boards has been pressed into service with Pogo Pins added to allow quick connections. But the calibrator sketch used the serial monitor. I wanted a stand alone version so here is my effort so far.
EDIT: It does give the correct numbers, the same as the "Example" sketch.

Pushing the encoder button changes the decade step, currently displayed as x100K.

Here are the pics of the finished mounting. The 2.5mm holes need to be tapped out to M3 (or 1/8) to suit.

The .stl files are included if anyone wants to make some.
The base suits my Arduino Nano VFO PCB, and the encoder/OLED display are on the IC22S replacement front.
