MGC - MeGARCard
The MGC is built as base development board with a set of push-buttons, leds, potentiometers and many more components on-board. It builds the base platform for a bunchset of adaptable microcontrolles (e.g. ATmega16A, ATmega4808, ESP32). It simplifies the development process by extending supported microcontrollers to a range of actuators and sensors. The board itself regulates the voltage to 5V or 3V3 automatically with a power mux (TPS2116). If 3V3 and 5V are suppored, the voltage can be changed on the dip switch of the adaptable microcontroller board. The base board supports a usb or uart-interface FT230XS to the adaptable microcontroller. The usb mode can be switched over a usb-multiplexer TS3USB30 within the dip switch on the base board. The leds on the base bord are controlled over a transistor array TBD62783 that keeps the input current on a very low state.
Note that the board should be disconnected from power sources when changing the state of the dip switches on the base or microcontroller adapter board.

Hardware
The pcb is created with KiCAD, the housing with FreeCAD. All files are built with github actions so that they are ready for a production environment.
PCB
The circuit board is populated on both sides (Top, Bottom). The best way for soldering the SMD components is within a vapor phase soldering system and for the THT components with a standard soldering system.
Top Layer
Bottom Layer
Mechanical
The housing has a tolerance of 0.2mm on each side of the case. So the pcb should fit perfectly in the housing. The tolerance can be modified with FreeCAD in the Parameter Spreadsheet.
