Diagrama de blocs

To Do

• Add buttons
• Add power input protection
• Add controls
• Resize boxes to same size (diagram)
• Change "targeta" to "targeta clauer"
• Restructure schematic for simplicity
• Add buttons to schematic
• Add expression for R (ISENSE)
• Change regulator to DC/DC (maybe + regulator)
• PCB v1
• Change 2nd crystal to 32kHz (instead of 8MHz)
• Correct via errors (DRC)
• Solve pcb model compatibility issues
• Rearrange power components
• Remove SPI
• Make budget for different production quantities
• Correct silkscreen
