Conexiones propuestas:
- U2 SDA → U1 pin 20 (SDA)
- U2 SCL → U1 pin 21 (SCL)
- U2 VCC → U1 5V
- U2 GND → U1 GND
- K1 filas → U1 pines 22, 23, 24, 25
- K1 columnas → U1 pines 26, 27, 28, 29
- K2 filas → U1 pines 30, 31, 32, 33
- K2 columnas → U1 pines 34, 35, 36, 37
- K1, K2 GND → U1 GND

- Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portaljharwinbarrozo43.0M
- Wirelessly connects power nets on schematic. Identical to the net portal, but with a power symbol. Used to organize schematics and separate functional blocks. To wirelessly connect power net portals, give them the same designator. #portal #powerjharwinbarrozo11.4M

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
