Endeavour-2 is an open-source printed circuit board by ScatteredDrifter, from the ScatteredDrifter/Endeavour repository on GitHub, published under the CERN-OHL-P-2.0 licence. It is a 2-layer board of 190.5 × 83.2 mm with 111 parts on 77 nets, routed with 1,213 tracks and 66 vias.
It is built around the ATMEGA32U2-AU and SRV05-4. Its parts include 39 diodes, 6 capacitors, 6 resistors, 2 ICs and 1 connector. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

The third iteration introduced a complete redesign of the pcb primarily to accommodate the RP2040 and BAV70 diodes.
I tried creating a circular positioning pattern for the components where their center is set with the mcu itself. Due to reposition of every component I rerouted the whole board again; also because Endeavour V¹ was one of my first designs and you can tell it was. A new silkscreen for both front and back of the pcb sets a different theme and clutters the whole board with ASCII-rubbish. This came into my mind because any actual drawing or pattern idea I had was blocked by my miserable ability to create art.
A new case accompanies this revision. Its not entirely done neither am I satisfied with its look and design. My abilities with CAD are limited and I lack the endurance ( will to use Windows or learn an alternative software) and time to make a better one or to create an actual good / decent design.
Nevertheless my current process is shared in this folder. I've tested the case with a previous rev pcb and could verify that its mostly working. The new case utilizes tadpole mount of some sort hence I ought to write a build guide.
For the previous versions of the PCB and Case look at the folders below:



Those are only renders, however I've printed a small test version already.

Cookpad Pad — A six keys macro pad made by Cookpad.
It measures 190.5 × 83.2 mm and has 2 copper layers, 1.6 mm thick.
111 parts, built around the ATMEGA32U2-AU and SRV05-4. 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 ScatteredDrifter/Endeavour repository on GitHub, at the commit this page was made from: the board is rev2/pcb/Endeavour-2.kicad_pcb and its schematic rev2/pcb/Endeavour-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
