Custom 4-layer IoT-Ready ESP32 Flight Controller PCB designed in KiCad 8 featuring USB Type-C, CH340C, MP1584 power management, MPU6050 interface, and manufacturing-ready Gerber files.
It measures 130.5 × 91.1 mm and has 2 copper layers, 1.6 mm thick.
128 parts, built around the CP2102-GM, MP1584EN, AMS1117 and AMS1117CD-3.3. 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 manhtienvu-vn/Defensive_Robot repository on GitHub, at the commit this page was made from: the board is 2. Hardware/Robot_Main_Controller_V3/Robot_Main_Controller_V3.kicad_pcb and its schematic 2. Hardware/Robot_Main_Controller_V1/STM32H723_SDC_Ver_1.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 manhtienvu-vn before reusing the design.
