The GCA is a board with a AT24CM0X EEPROM or any other compatible EEPROM. The board itself can be driven with a voltage from 3V3-5V and is used chainload games onto the GamePad over the integrated bootloader (currently under development).

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.
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.
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.
