Flashing Lights Triple Duo/README.mdFlashing Lights Triple Duo
This circuit consists of two 555 timers configured at different frequencies. These frequencies are selected so that red LED’s and blue LED’s alternatively flashes. Moreover each group (red or blue) flashes aproximately three times before colour is switched, similar to american police strobe lights.

Questions
How big is the TDA2050 PCB?
It measures 74 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TDA2050 use?
30 parts, built around the TDA2050V. 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 TDA2050 KiCad files?
From the jaka/electronics repository on GitHub, at the commit this page was made from: the board is Amplifier TDA2050 BTL/TDA2050.kicad_pcb and its schematic Amplifier TDA2030/TDA2030.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TDA2050 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaka before reusing the design.
