BirryGit/Battery-Powered-Meshtastic-BoardI want to learn how to make PCBs, and this seemed like a good idea. I originally was following the Stasis tutorial, but veered away from it significantly. I want to get into meshtastic, so this is awesome :)
Meshtastic LoRa is an open-source printed circuit board by BirryGit, from the BirryGit/Battery-Powered-Meshtastic-Board repository on GitHub. It is a 4-layer board of 30 × 61.1 mm with 31 parts on 58 nets, routed with 391 tracks and 199 vias.
It is built around the ESP32-S3-WROOM-1-N8, BQ24040DSQR and ESD7104MUTAG, with the TLV75801PDRV and USB4105-GF-A among its other parts. Its parts include 10 resistors, 7 capacitors and 3 diodes. It belongs with the radio and wireless boards and the ESP32 boards of this library.
This is an ESP-32-S3 powered LoRa board with a battery charger. It has a connected screen and external pins for I2C and power outputs. It has ESD protection.

It measures 30 × 61.1 mm and has 4 copper layers, 1.6 mm thick.
31 parts, built around the ESP32-S3-WROOM-1-N8, BQ24040DSQR, ESD7104MUTAG and TLV75801PDRV. 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 BirryGit/Battery-Powered-Meshtastic-Board repository on GitHub, at the commit this page was made from: the board is PCB/Meshtastic_LoRa.kicad_pcb and its schematic Schematic/Meshtastic_LoRa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask BirryGit before reusing the design.
