A custom-made PCB for the AS3340 IC
AS3340 is a voltage-controlled oscillator. This board is made with the specs specified in the datasheet of the AS3340, which can be found here.
I also included a 555-based negative voltage generator for this circuit, as the board specifies a need for it. Vcc is rated at 15V, and Vee is approximately -13V.

Questions
How big is the AS3340 PCB?
It measures 80 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AS3340 use?
40 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AS3340 KiCad files?
From the constlo/AS3340 repository on GitHub, at the commit this page was made from: the board is as3340.kicad_pcb and its schematic as3340.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AS3340 design in my own project?
Its repository states no licence, so its author keeps all rights: ask constlo before reusing the design.
