SolarDataLogger PCB
Lopfi/solar-logger
This is a simple box with an ESP32 with a LC12S, build to replace a DataBox24G from All of Solar, which communicates with a solar inverter to collect data on power generation.

This is a 1U rack PCB to hold 8 x ESP32S3 Wroom chips.
RACK ESP32S3 is an open-source printed circuit board by ccadic, from the ccadic/ESP32S3RACKPCB repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 482.6 × 44.6 mm with 188 parts on 373 nets, routed with 1,685 tracks and 280 vias.
It is built around the ME6211C33M5G-N and WS2812B. Its parts include 64 capacitors, 64 resistors, 9 connectors and 8 ICs. It belongs with the ESP32 boards of this library.

all the stuff you need to build your own FreeDeck


It measures 482.6 × 44.6 mm and has 2 copper layers, 1.6 mm thick.
188 parts, built around the ME6211C33M5G-N and WS2812B. 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 ccadic/ESP32S3RACKPCB repository on GitHub, at the commit this page was made from: the board is RACK-ESP32S3.kicad_pcb and its schematic RACK-ESP32S3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
