Divergence Meter Project v2 is an open-source printed circuit board by waicool20, from the waicool20/Divergence-Meter-Project-v2 repository on GitHub. It is a 2-layer board of 89.3 × 52.1 mm with 149 parts on 121 nets, routed with 1,055 tracks and 258 vias.
It is built around the SX1308, ME6211C30M5G and BQ24295RGE, with the DX-BT24-T, LM3481 and TS3USB221ARSE among its other parts. Its parts include 49 resistors, 43 capacitors, 10 ICs, 7 diodes and 7 transistors. It belongs with the STM32 boards of this library.
This is the second iteration of the Divergence Meter Project and another personal learning project, this time learning how to integrate Li-Ion batteries into a project, new electrical converter topologies, Rust Programming Language and IoT.
Hardware is mostly finalized and most of the work left to do is actually programming the thing to work like the first program along with IoT capabilities via Android companion app. README will remain brief until I actually finish working on this, stay tuned :)

TobleMiner/blinkekatze
Blinkekatze, a replacement PCB to turn cat themed night-lights into interactive light displays
It measures 89.3 × 52.1 mm and has 2 copper layers, 1.6 mm thick.
149 parts, built around the SX1308, ME6211C30M5G, BQ24295RGE and DX-BT24-T. 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 waicool20/Divergence-Meter-Project-v2 repository on GitHub, at the commit this page was made from: the board is Hardware/Main/Main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask waicool20 before reusing the design.
