I've come to the point where I need to move the RF synthesizer to a PCB. I am going to mount the encoder, D1 Mini, OLED, and Si5351 board all on a 60mm by 80 mm board. I'll put the display and encoder on one edge to interface with the operator through a box wall. I'm going to 3d print the box later, but I'm considering a shielded metal box, or something made out of clad PCB panels.
The photo below shows the candidate PCB. I got the PCB from an assortment sold on Amazon.com Link I still have to add a 3.3 volt power supply to the circuit. For this I'll need to measure the total current draw of all the components.
