IoT-based EV Fleet Management System for real-time vehicle monitoring and tracking.
It measures 132 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the SIM800L and L293D. 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 sui77/fetap-mobile repository on GitHub, at the commit this page was made from: the board is pcb/fetap.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 sui77 before reusing the design.
