Hold code and eventually the pcb layout for my hooting owl retrofit
Atmega hooting wiring is an open-source printed circuit board by PhysicsUofRAUI, from the PhysicsUofRAUI/hooting_owl repository on GitHub, published under the MIT licence. It is a 2-layer board of 42.1 × 40.9 mm with 16 parts on 30 nets, routed with 99 tracks and 15 vias.
It is built around the ATMEGA328-PU, LM317LZ and MCP1700-5002E/TO, with the CC0805KRX7R9BB104, CC0805KKX7R7BB105 and C0805C220J5GAC7800 among its other parts. Its parts include 6 capacitors, 4 ICs, 2 resistors, 1 transistor and 1 crystal. It belongs with the AVR (ATmega, ATtiny) boards of this library.

It measures 42.1 × 40.9 mm and has 2 copper layers, 1.6 mm thick.
16 parts, built around the ATMEGA328-PU, LM317LZ, MCP1700-5002E/TO and CC0805KRX7R9BB104. 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.
From the PhysicsUofRAUI/hooting_owl repository on GitHub, at the commit this page was made from: the board is atmega_hooting_wiring/atmega_hooting_wiring.kicad_pcb and its schematic atmega_hooting_wiring/atmega_hooting_wiring.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
