Ndambia/lilygo
A custom 4-layer KiCad PCB design integrating an ESP32 Wi-Fi/Bluetooth microcontroller with a SIM7600G-H 4G LTE Cat-4 cellular module, comprehensive power management, GPS tracking, GPRS connectivity, USB-C charging…

It measures 50 × 105 mm and has 2 copper layers, 1.6 mm thick.
64 parts, built around the ESP32-WROOM-32, CH340G, IRLML0030 and BAT54C. 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 f-zhuk/Dot-Matrix-Terminal repository on GitHub, at the commit this page was made from: the board is Hardware_BRD/Dot-Matrix-Terminal/Dot-Matrix-Terminal.kicad_pcb and its schematic Hardware_BRD/Dot-Matrix-Terminal/Dot-Matrix-Terminal.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 f-zhuk before reusing the design.
