Colpitts Oscillator, MiniPCB, 06A-20, Rev A1-01
I made a Colpitts Oscillator (06A-20) that oscillates at 261 kHz!
I mimicked one of the circuits that's been on Wikipedia since 2009. https://en.wikipedia.org/wiki/Colpitts_oscillator
Collect Components
The part number shown in the picture is wrong. The correct part number is 06A-20. This will be corrected in the next revision.
Solder Components
For ease, start with the shortest components.
Test With Digilent's Analog Discovery 2/3
Note the outputs are not inverted, and one is stronger than the other. The PCB silkscreen should be updated to only have one output (OUT+).
