XO106r5: Quad square-wave drone module with patchable logic and filter (PCB/panel)

A recent clearout has revealed a number of PCB/panel sets for the XO106r5 drone module. For more details about this module, check out the listing for the complete module. 

NOTE THAT THE PANELS ARE THE 'OLD STYLE' PURPLE PANELS - if you want one of the newer black panels then you'll have to make your own arrangements regarding fabrication.

In a similar vein, this listing is for the PCB/panels only - it is up to you to source all the necessary components for the build and flash the oscillator firmware onto the microcontrollers (ATTiny85 are recommended, although the firmware will fit on an ATTiny45). If you don't feel confident doing any of this, you may be better off with a complete module instead.

This isn't an ideal beginner's build - whilst there are few distinct components, none of which are inherently strange, there are a lot of them.
